Know Where You're Going
Be sure that you search the location of your interview the day before on Google Maps or a GPS. Make sure you know exactly where you're going, how to get there, how long the commute will be, and what the building procedures are to avoid getting lost and running late.
Research The Company
One important thing you can do to prepare for an interview is to do some extensive research on the company you're applying to beforehand.
Bring Your Resume
Always have your current, up-to-date resume in a file on your computer, as well as a neatly printed out copy that is ready to go whenever you may unexpectedly need it.
Be as accommodating as possible to the interviewer's schedule. It's a great way to make a good first impression and appear to be adaptable in any situation.
When asked if you have any follow up questions, don't just sit there and shake your head and say no. Ask questions. Brainstorm some potential questions you may have ahead of time so that once you're in the hot seat you don't freeze up and forget.
Get There Early
Traffic delays are beyond your control, so you’ll want to add in some extra time when commuting to your Interview. Get there early, but don't go in early. You don't want to show up a half hour ahead of schedule but you certainly don't want to show up even a minute late.
Dress To Impress
Pick out a suitable outfit to wear to an interview the night before and try it on. Make sure you feel comfortable while wearing it and that it is appropriate for the type of job you're applying for.
