Regeneron Process Development Engineer interview questions

After an initial HR Screening there was a one-on-one video call with the hiring manager. After that, there were panel interviews with 8 people, each a half hour. I have interviewed for two positions and made it to this stage - whether or not the panel interviews are onsite or virtual is dependent on the hiring manager's preferences and timing. Panels include the hiring manager, senior leadership in the open position's hierarchy and people that would work closely with the candidate.
