I had a total of 3 interviews. My first interview was a phone screen with the District Business Manager which lasted about 25 minutes. Two weeks later, I had a face-to-face interview over lunch with the District Business Manager and one of his counterparts. My final interview was with the Regional Sales Manager the following week. I received the verbal job offer a week and a half later and the written offer 3 days after that. Be VERY well prepared throughout the entire interview process. Pharmaceutical sales is a very competitive and difficult industry to get into so there's a lot of competition. You will be asked several behavioral questions. Make sure you share testimonials about how one of their prescription drugs has helped you or a relative and/or share testimonials of how Pfizer's over the counter medications have helped you feel better (i.e. Advil, Robitussin, Emergen-C, etc). Brag books are very important to reference during your interview. They help set you apart from other candidates and show a documented track record of success.
