Pfizer Principal Scientist interview questions

I spent full one day for onsite interviews. Seminar presentations and meeting with hiring manager, 2 of her bosses. The big boss was very rude and bully. One of the interviewer was rude, combative and was attacking me through out the interview. I was seated in very small room with up to 6 people which was even too small for 2 person. Everyone was repeating the same questions I was asked by previous panel. And the process was very tiresome and challenging.
