3 rounds, first round was self-video responses to basic behavioral questions, next was a skype with the manager (a bit more technical) and the third was another conversation with the manager where he described my role and asked if i would be interested.

I was sent a link to an online video interview portal – the interface was pretty user-friendly, but I found that it froze quite frequently (it could have been my connection, but normally things run pretty well on my computer). The first part of the interview involved recording an introduction, which can be uploaded as a file from your computer – to save time, try recording this ahead of time if you have this type of interview with Regeneron. The questions were all very standard, but it felt a little awkward talking into my webcam.
