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.
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 sure to include all of your skills and experiences in your cover letter and try not to repeat yourself as much as possible. Re-read your cover letter the night before to get an idea and overall understanding of what you plan on telling your new potential employer during the interview.
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 type of situation. When scheduling an interview, choose a time and date that best serves both you and the company. If something comes up and you need to reschedule, always give a heads up at least 24 hours ahead of time.
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.
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.
Clean up your social media
Do a quick sweep of your social media channels prior to your interview. Some employers will check up on your accounts to see what you're up to during your personal time and you want to make a good impression. Delete anything you wouldn't mind them seeing just to be on the safe side.
Be sure to get a good night's sleep the night before an interview, whether it be a phone interview or in-person meeting. You will want to be clear-headed and well-rested, because it’s going to show.
