The document provides general tips for overcoming an interview. It discusses treating an interview like a cautious climb up a mountain trail and preparing by flagging important life and career landmarks. It emphasizes the importance of preparation, including creating an outline of one's career and education, identifying strengths and weaknesses with examples, preparing for common questions, researching the company, and asking thoughtful questions. Interviews are seen as opportunities for both the employer and applicant to gather information about fit and qualifications. Thorough preparation, including self-reflection, research, and practice is key to performing well.

- 1. General Tips ToOvercome An Interview So what if you are not a mountaineer. Or a keen hiker. You still cannot treat your interview like a careless morning trot along a jogger's path. Your jaw-jaw at the interview table is nothing less than a cautious climb up a mountain trail--which begins around your early childhood and meanders through the years at the academia before reaching a new summit in your career.And as you retrace your steps down memory lane make sure that you post flags at important landmarks of your life and career, so that you can pop them before the interview panel scoops them out of you. You don't want to be at the receiving end, do you? Face the panel, but don't fall of the chair in a headlong rush-and-skid attempt to tell your story. Take one step at a time. If you place your foot on slippery ground, you could be ejecting out on a free fall. So prepare, fortify your thoughts, re-jig your memory, and script and design your story (without frills and falsity). Without the right preparation and storyboard, you could be a loser at the interview. Here are a few preparation tips that books on interviews sometimes overlook. Before the interview 1. Chronological Outline of Career and Education Divide your life into "segments" defining your university, first job, second job. For each stage, jot down : The reason for opting certain course or profession; Your job responsibilities in your previous/current job; Reason of leaving your earlier/current job. You should be clear in your mind where you want to be in the short and long term and ask yourself the reason why you would be appropriate for the job you are being interviewed for and how it will give shape to your future course. 2. Strengths and Weaknesses You should keep a regular check on your strengths and weaknesses. Write down three (3) technical and three (3) non-technical personal strengths. Most importantly, show examples of your skills. This proves more effective than simply talking about them. So if you're asked about a general skill, provide a specific example to help you fulfil the interviewer's expectations. It isn't enough to say you've got "excellent leadership skills". Instead, try saying: "I think I have excellent leaderships skills which I have acquired through a combination of effective communication, delegation and personal interaction. This has helped my team achieve its goals." As compared to strengths, the area of weaknesses is difficult to handle. Put across your weakness in such a way that it at leaset seems to be a positive virtue to the interviewer. Describe a weakness or area for development that you have worked on and have now overcome. 3. Questions you should be prepared for
- 2. Tell us aboutyourself. What do you know about our company? Why do you want to join our company? What are your strengths and weaknesses? Where do you see yourself in the next five years? How have you improved the nature of your job in the past years of your working? Why should we hire you? What contributions to profits have you made in your present or former company? Why are you looking for a change? Answers to some difficult questions : Tell me about yourself ? Start from your education and give a brief coverage of previous experiences. Emphasise more on your recent experience explaining your job profile. What do you think of your boss? Put across a positive image, but don't exaggerate. Why should we hire you? Or why are you interested in this job? Sum up your work experiences with your abilities and emphasise your strongest qualities and achievements. Let your interviewer know that you will prove to be an asset to the company. How much money do you want? Indicate your present salary and emphasise that the opportunity is the most important consideration. Do you prefer to work in a group? Be honest and give examples how you've worked by yourself and also with others. Prove your flexibility. 4. Questions to As At the end of the interview, most interviewers generally ask if you have any questions. Therefore, you should be prepared beforehand with 2-3 technical and 2-3 non-technical questions and commit them to your memory before the interview. Do not ask queries related to your salary, vacation, bonuses, or other benefits. This information should be discussed at the time of getting your joining letter. Here we are giving few sample questions that you can ask at the time of your interview. Sample Questions Could you tell me the growth plans and goals for the company? What skills are important to be successful in this position? Why did you join this company? (optional) What's the criteria your company uses for performance appraisal? With whom will I be interacting most frequently and what are their responsibilities and the nature of our interaction?
- 3. What is thetime frame for making a decision at this position? What made the previous persons in this position successful/unsuccessful? 5. Do your homework Before going for an interview, find out as much information on the company (go to JobsAhead Company Q and A) as possible. The best sources are the public library, the Internet (you can check out the company's site), and can even call the company and get the required information. The information gives you a one-up in the interview besides proving your content company or position. Clearing the interview isn't necessarily a solitary attempt. Seek assistance from individuals who are in the profession and whose counsel you value most. Be confident in your approach and attitude; let the panel feel it through your demeanour, body language and dressing. Getting prepared for your interview is the best way to dig deep and know yourself. You will be surprised that it would breed a new familiarity become more familiar with your own qualifications that will be make you present yourself better. All the best and get ready to give a treat. The Interview Interview is an opportunity for both the employer and the applicant to gather information. The employer wants to know if you, the applicant, have the skills, knowledge, self-confidence, and motivation necessary for the job. At this point you can be confident that the employer saw something of interest in your resume. He or she also wants to determine whether or not you will fit in with the organization's current employees and philosophy. Similarly, you will want to evaluate the position and the organization, and determine if they will fit into your career plans. The interview is a two-way exchange of information. It is an opportunity for both parties to market themselves. The employer is selling the organization to you, and you are marketing your skills, knowledge, and personality to the employer. Interview Preparation Research is a critical part of preparing for an interview. If you haven't done your homework, it is going to be obvious. Spend time researching and thinking about yourself, the occupation, the organization, and questions you might ask at the end of the interview. Step 1: Know Yourself The first step in preparing for an interview is to do a thorough self-assessment so that you will know what you have to offer an employer. It is very important to develop a complete inventory of skills, experience, and personal attributes that you can use to market yourself to employers at any time during the interview process. In developing this inventory, it is easiest to start with experience. Once you have a detailed list of activities that you have done (past jobs, extra-curricular
- 4. involvements, volunteer work,school projects, etc.), it is fairly easy to identify your skills. Simply go through the list, and for each item ask yourself "What could I have learned by doing this?" "What skills did I develop?" "What issues/circumstances have I learned to deal with?" Keep in mind that skills fall into two categories - technical and generic. Technical skills are the skills required to do a specific job. For a laboratory assistant, technical skills might include knowledge of sterilization procedures, slide preparation, and scientific report writing. For an outreach worker, technical skills might include counselling skills, case management skills, or program design and evaluation skills Generic skills are those which are transferable to many work settings. Following is a list of the ten most marketable skills. You will notice that they are all generic. • Analytical/Problem Solving • Flexibility/Versatility • Interpersonal • Oral/Written Communication • Organization/Planning • Time Management • Motivation • Leadership • Self-Starter/Initiative • Team Player Often when people think of skills, they tend to think of those they have developed in the workplace. However, skills are developed in a variety of settings. If you have ever researched and written a paper for a course, you probably have written communication skills. Team sports or group projects are a good way to develop the skills required of a team player and leader. Don't overlook any abilities you may have When doing the research on yourself, identifying your experience and skills is important, but it is not all that you need to know. Consider the answers to other questions such as: • How have I demonstrated the skills required in this position? • What are my strong points and weak points? • What are my short term and long term goals? • What can I offer this particular employer? • What kind of environment do I like? (i.e. How do I like to be supervised? Do I like a fast pace?) • What do I like doing? • Apart from my skills and experience, what can I bring to this job? Step 2: Know the Occupation The second step in preparing for an interview is to research the occupation. This is necessary because in order to present a convincing argument that you have the experience and skills required for that occupation, you must first know what those
- 5. requirements and dutiesare. With this information uncovered, you can then match the skills you have (using the complete skills/experience inventory you have just prepared) with the skills you know people in that occupational field need. The resulting "shortlist" will be the one that you need to emphasize during the interview. It is also in your best interest to identify the approximate starting salary for that position, or those similar. There are several ways to find out about an occupation: • Acquire a copy of the job description from the employer (Human • Resources/Personnel) or check with Student Employment Services. If you are responding to an advertisement, this may also supply some details. The Career Resource Centre has general information files on a variety of occupations. Make sure you have read through the appropriate file and are updated on the occupation. If you belong to a professional association related to the occupation, use its resources. These associations often publish informative newsletters and sponsor seminars. It is also a good way to meet people working in the field. Conduct information interviews with people working in the field. Read articles about people in the occupation, and articles written by people in the occupation. Sources include newspapers, magazines and the internet. Find out what the future trends are in the area. Is technology changing the job? Step 3: Know the Organization The more you know about an organization, the better prepared you will be to discuss how you can meet its needs. Some of the characteristics that you should know about an organization are: • Where is it located? • How big is it? • What are its products and who does it serve? • How is the organization structured? • What is its history? • Have there been any recent changes, new developments? There are a number of ways in which you can access this information. Most medium- to large-sized organizations publish information about themselves. You can access this a number of ways: • On campus at the Student Employment Services (company literature and business directories) or at the Drake Centre Library • The Winnipeg Centennial Library has a business microfiche with information on over 5000 Canadian companies and business directories • Many companies have internet home pages which you can locate by searching by industry and company name • Finally, you can visit or phone the organization and request some information on their products, services or areas of research If the organization is fairly small, or fairly new, there may not be much information published. In this case, it will be necessary to do an information interview. Contact
- 6. someone within theorganization, introduce yourself, explain that you are considering moving into the field, and ask if it would be possible to meet with him/her to inquire about the company/organization and about what exactly the position would involve. Step 4: Prepare Questions Having completed your background research, you are now ready to prepare questions to ask the interviewer(s). Try to think of questions for which the answer was not readily available in company literature. Intelligent well thought-out questions will demonstrate your genuine interest in the position. Be careful how many questions you ask, however, as too many can imply you feel the interview was not successfully run. Pick your questions with care - this is your chance to gather information, so ask about what you really want to know. Avoid sounding critical by mentioning negative information you may have discovered. This is one of the most effective ways to compare different employers, so for issues of particular importance to you (for example, whether they support staff upgrading), you should ask the same questions of each employer. Some sample questions are: • What are the most significant factors affecting your business today? How have changes in technology most affected your business today? • How has your business/industry been affected by the recession? • How has your company grown or changed in the last couple of years? • What future direction do you see the company taking? • Where is the greatest demand for your services or product? • Where is most of the pressure from increased business felt in this company? • Which department feels it the most? • How do you differ from your competitors? • How much responsibility will I be given in this position? • What do you like about working with this organization? • Can you tell me more about the training program? • Have any new product lines been introduced recently? • How much travel is normally expected? • What criteria will be used to evaluate my performance? • Will I work independently or as part of a team? • How did you advance to your position? • What are the career paths available in this organization?
- 7. • When canI expect to hear from you regarding this position? It is very important to ask the last question because employers want to hire individuals who are interested in the position - and asking this question definitely helps to demonstrate interest on your part. Exercise judgement when asking questions to an employer. When being interviewed by a large company that has a high profile, one would not ask the question "What is the history of your company and how was your company started?" You can find the answer to this question in the company's annual report or articles in magazines/newspapers. However, small- and medium-sized companies do not always produce publicly available annual reports and it may be difficult to access information on the company and its role in the industry. This question is appropriate if you have exercised all other ways to find out the answer. How To face The Interview 1.Are your work practices similar or different from ours?

PRECAUTIONS TO TAKE-UP BEFORE YOU ENTER THE INTERVIEW ROOM For your first few interviews your background is important - your school, the medium and the place you studied in, all serve to give the interviewer an idea about you. Carry a copy of the bio-data that you have already sent, and the interview letter. Keep the extra copy with you, just in case. Show the interview letter to the receptionist/interviewer to establish your credentials, but keep this letter with you. This gives you, for your future reference, a time and date record of your interview, gives the official address of the company for further correspondence and clarifications, and may give you the name and designation of the person you are to report to. Carry everything you need for the interview in a neat folder - do not have loose papers cascading to the floor because you are desperately hunting for the degree certificate, while the interviewers drum their fingers impatiently. And don't carry your papers in a plastic or cloth shopping bag either: invest in a good folder, plastic or even leather. Incidentally, don't feel shy or hesitant about calling up the office and getting details about location, landmarks/bus routes/other information to help you reach the venue of the interview. Again, if it is not a "mass" interview, where lots of people are being interviewed on the same day, and you do have a genuine difficulty about reaching on the scheduled day/time, many employers will re- schedule if you ask them nicely enough. The reverse is also true: a good impression is created if you take the trouble to inform the interviewer that you can/will not attend the interview. If you are in the same town go and "case the joint" - see where the
- 9. office/interview centre is,and how long it will take you to get there. Always arrive at least fifteen minutes before your scheduled time - that gives you time to catch your breath in case you climbed the stairs too fast, allows you to compose yourself and not be too nervous, and to check out the competition. If the interview is in the offices of the company itself, this also allows you to get a "feel" of the company. See how comfortable you feel, how efficient the interview process is. Says a lot about what the rest of the company When you are facing a panel of interviewers, make your best moves. Whether you are searching for jobs, looking for career avenues or climbing the corporate ladder, you can't escape team interviews these days. The problem is that such interviews don't have a pattern to them. They come in different forms. You could be facing your prospective team members. Or you could be up against the top brass—HR vice-president, the section head, the operations chief. Or you could also be sent to a recruitment assessment centre for multi-parametric evaluation (psychological tests for pressure-handling abilities, team-player skills and so on). Try these ten tips for surviving, and scoring, in a team interview. GIVE VARIETY TO YOUR ANSWERS Remember you might be interviewed by different panels. Don't give a stock answer to all of them. They'll be comparing notes. Repackage your skills so that they sound different. If you're showcasing project X as your major achievement in your present job before one team, talk about project B before another interview panel. A technical team will tune in to techie talk; an HR team would rather hear about your interpersonal skills. FINE-TUNE INTERPERSONAL SKILLS Pull out the stops on your group management and group presentation skills. Interviewers are people after all. Look for the personality type underscoring each interviewer.Then try and connect with each one of them without getting personal. Usually the best way to make contact is to project values that you feel you can share with your interviewers. DON'T QUAKE IN YOUR BOOTS • Interviewers are not ogres. They are looking for excuses to hire you, not spill your guts. • Don't be obsequious. That conveys low self-esteem.
- 10. • If youface your interviewers with fear in your eyes, they won't like what they see. They are NOT sadists. PREPARE FOR STRESS • You'll be up against a time crunch in a team interview. • In one-on-ones, the interviewer might be taking notes, allowing you little breathers. No such luck with four people firing questions at you. Use stress control techniques to soothe your nerves. You might even use the extra adrenaline to sharpen your responses. SHOWCASE THE IMPORTANT THINGS • List seven important things that fit the job description of the advertised post. Prepare to present skills that fit such traits. • It helps to talk to friends familiar with the job description. You can even ask them to prepare tests that you can take from them. REHEARSE WELL • Put together three family members or friends with diverse personality traits. • Recreate the formality of a team interview situation and ask them to fire nonstop questions at you. That will serve as a useful practice session. • Ask for serious feedback, especially about weak areas in your answers. Questions about qualifications and work experience are usually generic, so what your mock team asks you is bound to be pretty close to the real stuff. CREATE A MENTAL PICTURE OF YOURSELF Boost your self-confidence by seeing yourself as star performer who's a cut above. See yourself answering with elan the questions you expect. Then replay your answers and ask yourself these questions: • How interesting were your observations? • Did most of your responses begin the same way? • Did you use 'we' often, suggesting team-player attributes? • Are there traces of humour in your responses? ASK GOOD QUESTIONS • Research is integral to a good interview performance. Find out as much about you can about the company concerned. Browse the Net, check company reports, put together news clips. • Armed with your background brief, ask relevant questions about the company. • If you think you have a bright idea about any ongoing activity, try this: "Did the company consider this option ..." LOOK BEYOND THE OBVIOUS
- 11. • Your interviewteam has some core queries about you. It's these they want you to address. Try and look beyond the upfront questions to decipher their exact intent. Then respond to fill in what the team is really looking for. • Flesh out your answers to focus on the team's concerns. If they ask you about your perception of the company's ESOP policy, they want you to present your expectation from a stock option plan. • Answer in sync with the general tenor of the interview. If your work involves individual research besides team work, don't go overboard about team-player abilities. Balance your answer. Mention how sometimes individual work is more productive though team work is needed to put into action ideas generated by individual research. Move through Question Papers Facing the technical interview of a company is an uphill task. It all depends on the mood of the interviewer and to an extent on your appearance. If he is in a bad mood, the interview can be really tough. Otherwise you might have a slight consideration. Be prepared for any questions from every section of your skill set. If the interviewer goes to a part of your skill, which you are not comfortable with, try to divert his attention to some other part in which you are an expert. Try to explain things in a simple way and be precise in your answers. If you don't know an answer admit it. DO NOT try to make up and answer. That might lessen your chances of getting through.

Whether you are searching for jobs, looking for career avenues or climbing the corporate ladder, you can't escape team interviews these days. The problem is that such interviews don't have a pattern to them. They come in different forms. You could be facing your prospective team members. Or you could be up against the top brass—HR vice-president, the section head, the operations chief. Or you could also be sent to a recruitment assessment centre for multi-parametric evaluation (psychological tests for pressure-handling abilities, team-player skills and so on).
- 21. Try these tentips for surviving, and scoring, in a team interview. GIVE VARIETY TO YOUR ANSWERS Remember you might be interviewed by different panels. Don't give a stock answer to all of them. They'll be comparing notes. Repackage your skills so that they sound different. If you're showcasing project X as your major achievement in your present job before one team, talk about project B before another interview panel. A technical team will tune in to techie talk; an HR team would rather hear about your interpersonal skills. FINE-TUNE INTERPERSONAL SKILLS Pull out the stops on your group management and group presentation skills. Interviewers are people after all. Look for the personality type underscoring each interviewer.Then try and connect with each one of them without getting personal. Usually the best way to make contact is to project values that you feel you can share with your interviewers. DON'T QUAKE IN YOUR BOOTS • Interviewers are not ogres. They are looking for excuses to hire you, not spill your guts. • Don't be obsequious. That conveys low self-esteem. • If you face your interviewers with fear in your eyes, they won't like what they see. They are NOT sadists. PREPARE FOR STRESS • You'll be up against a time crunch in a team interview. • In one-on-ones, the interviewer might be taking notes, allowing you little breathers. No such luck with four people firing questions at you. Use stress control techniques to soothe your nerves. You might even use the extra adrenaline to sharpen your responses. SHOWCASE THE IMPORTANT THINGS • List seven important things that fit the job description of the advertised post. Prepare to present skills that fit such traits. • It helps to talk to friends familiar with the job description. You can even ask them to prepare tests that you can take from them. REHEARSE WELL • Put together three family members or friends with diverse personality traits. • Recreate the formality of a team interview situation and ask them to fire nonstop questions at you. That will serve as a useful practice session.
- 22. • Ask forserious feedback, especially about weak areas in your answers. Questions about qualifications and work experience are usually generic, so what your mock team asks you is bound to be pretty close to the real stuff. CREATE A MENTAL PICTURE OF YOURSELF Boost your self-confidence by seeing yourself as star performer who's a cut above. See yourself answering with elan the questions you expect. Then replay your answers and ask yourself these questions: • How interesting were your observations? • Did most of your responses begin the same way? • Did you use 'we' often, suggesting team-player attributes? • Are there traces of humour in your responses? ASK GOOD QUESTIONS • Research is integral to a good interview performance. Find out as much about you can about the company concerned. Browse the Net, check company reports, put together news clips. • Armed with your background brief, ask relevant questions about the company. • If you think you have a bright idea about any ongoing activity, try this: "Did the company consider this option ..." LOOK BEYOND THE OBVIOUS • Your interview team has some core queries about you. It's these they want you to address. Try and look beyond the upfront questions to decipher their exact intent. Then respond to fill in what the team is really looking for. • Flesh out your answers to focus on the team's concerns. If they ask you about your perception of the company's ESOP policy, they want you to present your expectation from a stock option plan. • Answer in sync with the general tenor of the interview. If your work involves individual research besides team work, don't go overboard about team-player abilities. Balance your answer. Mention how sometimes individual work is more productive though team work is needed to put How to write that Winning Resume for your Dream job If you are a new entrant in the job market, you need to perfect your resume before applying for your 1st job Since you are fresh out of college, use your education as your strong point. Aggregate %, CGPA, accolades, club participation, etc. will be your focus. "Do I really need a resume? What should I write in my resume?"
- 23. These are questionswhich worry every college graduate looking for his/her first job. Welcome to the real world! Yes you really need to make your resume and how you present yourself in that resume will go a long way towards getting you your first job. It's a myth that resumes of entry-level graduates are unimportant because they lack the 'pull' of experience. Nothing could be further from the truth. Not only is a well-made resume important for every job seeker, it is more critical for entry level graduates. A resume is a mirror of your professional identity. A well-defined resume impresses a recruiter. A sloppy resume immediately proclaims the candidate to be sloppy. Here are some do's and don'ts on what makes a great resume for graduates seeking entry-level positions in industry. OBJECTIVE One of the most frequently heard complaints made by recruiters about entry-level resumes is that they lack a specific objective. Resumes of fresh graduates have fuzzy, general objectives or no objective at all. Mentioning a specific objective is by far the most important feature of an entry- level resume. Without goal clarity you are bound to drown in the sea of mediocrity. The only thing worse than the absence of an objective is a vague objective. Something like "My objective is to work with a dynamic company which will fully utilise my talents…" is a complete no- no! This objective is worthless because it gives the potential employer no idea about your goals or your direction. Your objective should be clear, well-defined and short-not more than 10-12 words.. It should be aimed towards getting a particular position in a specific industry. Thus your objective should talk about the following: 1. Position wanted 2. Functional area 3. Industry wanted Examples of good objectives: Example 1: "Junior management position wanted in PROGRAMMING/ engineering field in IT industry.' Example 2: GET in position in the manufacturing field. Example 3: Entry level programmer in a software development company. Example 4: Marketing position in the FMCG segment of a Multinational Company. Example 5: Multimedia software development position. Open to Relocation. Example 6: "A position as a Production supervisor with a petro-chemical company." SUMMARY Summary is the second most important factor that is conspicuous by its absence in resumes of entry-level graduates. It is a good idea to include a summary of your resume after having mentioned your objective. This sums up your resume in a nutshell and gives you an opportunity to highlight your strengths. It invites the recruiter to read your detailed resume. The summary should consist of 4-5 specific points-either bulleted or in one paragraph. Sample Summary 1: • B.E (Computer Science) from IIT-Delhi, in 2000. • Course in Computers Database programmes Oracle 8I & VB6 from PENTASOFT in 2005. • Consistently good academic record. • Good analytical and communication skills. • Have worked on a curriculum project "XXX XXXXX XXXX" Sample Summary 2: "Masters in Computer Application with specialisation in J2EE/Web Technologies. Great operational, communication and computer skills. Good academic record throughout. Among the top three students out of a batch of 120 students. Undergone Industrial training in a top petrochemical Company.
- 24. EDUCATIONAL QUALIFICATIONS Most fresherresume doesn't suffer from space constraint . However it is a good idea to include only those educational and professionals qualifications which are relevant. Put your qualifications in a reverse chronological order. i.e. the recent ones first followed by earlier ones. Entry level resume should also mention the names of their school and college, years in which they passed their board examinations. However, include your marks only you have shown a good academic performance. WORK EXPERIENCE An entry- level resume cannot compete with resumes of experienced workers in the area of work experience. But don't forget to list internships, voluntary work and summer training that you have undertaken. How you present these is very important. Make sure you clearly define your duty and responsibilities during this training. E.g.: "Worked as a summer trainee in India's largest Oil Refinery. I was working for the system control department. Wrote quality reports as well as ISO features for the company." Any projects done for your school or your college should also be mentioned. DESIGN Follow a simple design, which gives maximum information in the minimum number of pages. Use an easy to read and commonly used font like 'Times New Roman' or 'Verdana.' Limit your font size to 10-11. Do not underline heavily. WORD USAGE Simple language, lucid expression with good grammar is the thumb rule. Watch your tenses carefully. Use short and simple sentences. And never-ever make the mistake of using long words just to impress the recruiter. Flowery words are for speeches, keep them away from your resume. OUCH! THE TRUTH HURTS There are many things we would rather not write in our resumes. And while writing a resume the strong temptation to stretch the truth (or simply lie through our teeth) can be quite overpowering. But just stomp on the temptation. Most companies opt for a reference check during recruitment. Your resume is considered a legal document and fudging up small details may cause you great embarrassment in your career. All right! so you've made yor resume. But this is not the time to sit back and relax. There are some important post-resume do's left. CHECK, AND RE-CHECK! The most important post resume step: Read and re-read your resume for any mistakes. Check the facts, the grammar, the spellings. After you have checked it, get you parents, friends, teachers to check it for you. One small mistake may cost you your job. And finally...mom is right you know! Do not procrastinate over anything, specially making your resume. Most fresh graduates prefer to leave the unappealing task of resume making till the last minute i.e the day before their first interview. However, remember that making great resumes take time and effort.
