I applied online. The process took 7 weeks. I interviewed at Regeneron (Limerick, Limerick) in Dec 2019
Interview
Two back to back on site interviews, nothing too hectic. Everyone was very nice and they questions were very reasonable and fair, gave a very detailed account of the role i would be doing and made sure I knew all there was to know about it - had no problem in answering any of my questions re working environment etc.
