An interview is a formal meeting between a job applicant and employer where they exchange information to determine if the applicant is suitable for the position. Common interview questions include asking about one's background and experience, strengths and weaknesses, reasons for being the best candidate, and why the employer should hire them. Some tips for interviews are to dress professionally, arrive early, maintain eye contact, be prepared to discuss achievements, and ask clarifying questions. Things to avoid include lying, giving one-word answers, asking about compensation, discussing personal issues, acting desperate, being unprepared, and having cell phones ring. The key is to be confident, give concise answers, remember good etiquette, and think of yourself as the best candidate.
