AstraZeneca Scientist interview questions

I got the interview through a employee referral. I was email communicated for telephone interview. It was a 1 hour telephone interview by Hiring Manager. A basic discussion on needs of the job and my interest including some of my research work. After a week I got a call saying I am scheduled for onsite interview and a HR telephone interview. The HR telephone interview is taken by a contract agency. Just simple basic questions. Coming to the all important onsite interview. The onsite was day full of interviews by various engineers and scientists. I met around 15-16 different people. I also gave a presentation lasting 1 hour in the middle of the day. All questions during the day were basically about my past work, team work, goals, work ethic etc. Each of the 15 people had a different way of asking questions. So I would recommend being confident with your answers and be yourself. My 1 hr presentation questions were geared towards my research work as expected. I got an email after 3 months saying I am not selected. I was pleased with my interview performance but unfortunate.
