Biogen Manager interview questions

I had a screening call followed up an interview with the hiring manager followed up 4 seperate interviews with their panel. I had a poor interview experience. Interviewers canceled at the last minute, showed up late, did not answer my questions clearly, could not understand why they were interviewing me, cut me mid-interview, and misprounced my name. The talent team handed me off from person to person, so I didn't know who the right contact person was. They asked for my availability for interview scheduling and they did not respect that. They told me they would get back to me by the end of the week and then didn't get back to be until the following week. They gave me an offer and gave me benefits information only hours before the offer. I initially accepted the offer but then was getting push back to start sooner. Then I had a covid scare with my children and the recruiter was rude about the fact that I wasn't responding back. I declined the offer as I don't think there is any amount of money where I can withstand so much disrespect.

A couple of rounds of interviews, where you speak the recruiter, hiring manager, and a few other folks. There were both behavioral as well as some technical questions throughout the process.
