Have a dress rehearsal:
Another way to plan ahead and feel more at ease is to have a full-on “mock” dress rehearsal of the interview. Pick out your outfit, get all of your documents in order and have a friend or relative interview you. Here, your “interviewer” will be able to help point out your strengths and weakness as well as address any mannerisms you may need to correct; for example, you may use too many informal words like “totally and awesome” or speak way too quickly which can hinder your chances of getting hired.
As part of the dress rehearsal it may also be a good idea to actually take a quick drive-by to where your interview will take place. This can ensure that you don’t get lost on the day of (Google Maps is not always reliable) and can give you an opportunity to check out the parking situation. Even if you know where you’re going, make sure to give yourself plenty of time to get there on the day of and ask for the interviewers direct phone number—accidents do happen and if you get into a car collision or there is far more traffic than you anticipate, you need to call immediately and let the interviewer know you will be running late or need to reschedule.
