I was scheduled to meet with the HM one week after the recruiter call. I had two meetings for the second round, one with a director and a marketing manager (30 min), and another one with two application scientists (1 h). My last round of interview happened the following week and lasted 90 minutes, including a technical presentation and other things they specifically asked for. Over 70% of the questions I got were highly technical, about the details of my past lab experiences. The team was friendly and professional, and they also gave some feedback on some of my answers.
