Practice makes perfect. Conduct practice interviews with a friend or family member, and ask for their feedback. You can also record or videotape your responses so you can review your answers and check your body language.
Prepare answers to commonly asked interview questions. Doing so will help you analyze your background and qualifications for the position. You don’t need to memorize answers, but having an idea of what you’re going to say will help you frame a solid response.
Also be ready to respond when you’re asked if you have any questions for the interviewer. Prepare a list of questions you want to ask the interviewer. Remember, you aren’t simply trying to get the job — you are also interviewing the employer to assess whether this company and the position are a good fit for you.
The more you practice, the more self-assured you will feel walking into the interview. Your answers will feel natural, and interviewers will be impressed by your confidence.
