One round interview with research team that lasted three hours. First interview had technical questions and the remaining time was spent on fit questions. I was notified within a few days that I had received a verbal offer from the research team and that I would have a phone interview with the director of research prior to receiving a formal offer. Director of research wanted to try to get a feel over the phone, but in the end, the decision came down to the research team and not the director of research.
