The interview was alright except for the fact that the hiring manager told me straight up that it was his first ever interview...it was obvious he wasn't sure how to go about the interview.

First round interview with HR. Next day second round interview with hiring manager. Reached out to HR three times over email over the course of six weeks without a response. Extremely Unprofessional no never respond again. Still no answer and job posting has been taken down. It is abhorrent the lack of care for potential employees. I will not apply nor recommend Regeneron to anyone in the future.
