Biogen Research Associate interview questions

It was a hour long interview.A lot of questions in detail.They exactly knew what they were looking for.I tried my level best in answering but maybe they were looking for a specific skill which i dint have

I was contacted by a recruiter who was hired by Biogen to find someone to fulfill the role and that recruiter reached out to my former boss who recommended me for the position. Once the recruiter contacted me I was invited to meet in person with them informally and then they recommended me to Biogen. I did not have a formal interview with Biogen as they needed someone quickly and had a good relationship with the recruiter. I did have to meet/interview with several people that I would be coordinating with offsite but once I got to Biogen I went directly to work (no interview with Biogen directly).
