It is common to feel nervous before an interview, but remember that the interview is essentially just a conversation for you and a prospective employer to get to know each other. This is your chance to learn more about the job role and company, as well as an opportunity for you to present yourself and your skills. It may be tempting to say what you think an employer wants to hear, but ultimately, you need to be a good fit for a company just as much as a company needs to be the right fit for you. The biggest factor that will affect the success of your interview is your preparation for the interview. You will feel more confident during an interview if you give yourself enough time to be ready in advance.
