Biogen Manager Manufacturimg interview questions

Wrong address for company was on interview agenda. Several people on interview schedule were not available for the three hour interview . Awkwardness sitting room for long periods of time without interviewers. Shuffled from room to room and seemed to be a mix up with reserved rooms. Part of interview was over lunch but no food was provided. The department lead only had a few minutes to meet with me and stated calendar was overbooked. Waited for nearly 30 minutes for an escort back to security desk at end of interview.
