I applied online. The process took 3 weeks. I interviewed at Regeneron (Tarrytown, NY) in Feb 2023
Interview
It's Two round interview process, Initial screening is for 30 min and the next one is for 5 hours, including break times. I believe the 5 hours interview is kind of a bad strategy. Repeating the same answer 6 times, people usually lose interest to answer by 3rd time. Done through the Teams.
