Non-engineering jobs
 Logistics
 Operations management
 Patent law and intellectual property
 Procurement, purchasing and buying
 Supply chain management
 Teaching, academia and lecturing
 Technical consulting
 Technical sales, marketing, business development
 Technical training
Pay Packet
 ME graduates fetch salaries from Rs 20,000 – 25,000 in the beginning.
 After gaining +2 years of work experience, you can get a salary of Rs
40000 - 60000.
 Candidates who get opportunities to work in overseas project get
numerous benefits and incentives which may even go to six figures.
 However, the salary depends upon some factors such as the state of the
industry, work experience, qualifications and ability of the candidate,
etc. amongst others.
 ME graduates who are in teaching can fetch a salary of >Rs 20000 plus
dearness allowances and other benefits.
Skills Map
Why focus on practical knowledge?
 There is a gap between engineering course content and the
requirements of the engineering services industry
 Engineering education system imparts knowledge on various
technical/non-technical areas, it often falls short of meeting the
expectations of the real world.
 One reason for this gap is a fundamental lacuna in the engineering
education framework. This is the only profession where an individual
goes from an academic programme directly into a job, with no prior on-
the-job training.
 “Getting fresh graduates ramped up quickly to productivity is a key
concern across the industry, graduates sometimes take six months to a
year to become productive.
 When fresh graduates enter the working environment, they have lots of
theoretical knowledge which is redundant, rather than the necessary
practical knowledge.”
 Most of our institutions and universities lag behind the rest of the world
in research output.”
Why Do an Internship?
 Gain Work Experience: First and foremost, internships and co-ops help you
gain experience. Classroom knowledge is important and makes you
competitive for internships, but practical knowledge in an industry is what
attracts employers.
 Create a Competitive Edge in the Job Market: This is probably the biggest
advantage. The experience you gain will give you a very competitive edge
when you start your job search. You will have concrete examples of work
experience to discuss during your interview. A guaranteed question during an
interview will be about your work history and internship experience.
 Networking Opportunities: One of the most popular ways of finding a job
is through networking. Doing an internship significantly increases your
networking opportunities by connecting you with professionals in your
chosen field. Networking also allows you to develop references who can
attest to your abilities.
 Job Transition: What better way is there for an employer to test a potential
employee than through an internship? This “try-before-you-buy” approach is
a significant advantage for the employer and can easily lead to a full-time job.
Successful interns are frequently offered permanent employment at their
internship site after graduation.
Why Do an Internship?
 Decide if a Field is Right for You: You can research the industry, but
there is no more effective way of finding out if you like something than
actually doing it. You also get all of your questions answered by industry
professionals while being immersed in the field.
 Apply Classroom Knowledge to the Real World: Preparing
academically for your career shows your intelligence and ability to learn,
but internships give you the opportunity to apply your knowledge to the
real world and develop your qualifications.
 Develop your Resume and Build Confidence: A robust application
(often a resume and cover letter) and a powerful interview are ultimately
what set successful candidates apart in the job search process. Internships
help you prepare both by giving you the experience and skills to build a
strong resume and the confidence to give an outstanding interview. When
you discuss your knowledge, skills and abilities, you will speak from
experience, not conjecture.

Final advise
 Many opportunities – plan your focused area
 Work on both mini and major projects
 Get the deep insight of the technology
 Write papers for reviewed journals, conferences
 Volunteer speaking on your specialized area
 Read, Read and Read
 Do not postpone the activity and try to finish on the defined
date.
 Work in the team for the project and share the ideas
 Be sincere, hard work and with good attitude
 Look for clarification if you have doubt.
 Get one or two internship projects with industry
All the best
