I applied online. The process took 1+ week. I interviewed at Regeneron (New York, NY) in Apr 2012
Interview
call interview fairly quick and simple
No questions on technical components
The interview was based on several established questions and less of a conversation
After the call I was told of my offer and started as the summer began
The interviewer was very nice and respectful. It was evident that she is passionate about her work and eager to share her expertise. It is a shame I wasn't offered a chance to join the company, but my positive experience encourages me to try again in the future.
Hirevue and then meeting with several teams they think you're a fit for, non technical but might ask technical questions depending on role. Pretty casual but your experience at the company is very team dependent
Overall there were two interviews. One HireVue technical that also asked you to complete some details (like start time, salary, etc.) and one interview with your manager, Pretty standard interview
