The interview took 3 months. I still haven't heard back from them after my last interview 4 weeks ago. I wish they would be more organized and professional with this process and let those who are not going to receive an offer know. First interview was a phone screening with the Regulatory Affairs Specialist and the Product Manager. A few weeks later I was invited for a second round interview/presentation. I was given a research prompt for this second interview to present on. This interview was with 5 people. I was then invited to go onsite for another interview. During this interview I was asked to do another presentation and had 3 rounds of interview with panels.
