6 interviews in the course of consecutive days. i appreciated the efficiency and fast decision making - I guess there was a rush to fill this position. During the interviews I felt comfortable, and I appreciated the conversations rather than feeling interrogated! It was a good experience

Question 1
What strategy I would propose based on current state of the company
I applied online. I interviewed at Regeneron (Belfast, Northern Ireland) in Feb 2026
Interview
Lengthy, multiple 30 min interviews with various individuals including the recruiter, hr, other members of the department. they are back 2 back so they were not extended and on time. they organised all efficiently
It was the usual, nice and informal on both ends. Had a second interview with whom would be my possible supervisors and never heard any response. A decline would be nice, and normal procedure.
