It's a matter of opinion, but I wouldn't focus too heavily on a "brag book" full of your accomplishments. You should certainly bring a pen and something to write on, as well as additional copies of your resume. Also, bring your PMA ( pharmaceutical industry jargon for Positive Mental Attitude).

Make sure that you are on time, etc. There are many interview books and articles out there that go into detail regarding interview etiquette.

Go over your resume because the interviewer should have a copy in front oh him as he interviews you. Make sure you know the timelines of your employment or schooling.

You should look professional and well groomed.
