after a phone interview there was a full day interview.. This started with a presentation ~45 minutes long plus questions. Next there were multiple 1 on 1 and 2 on 1 interviews with team members. Questions were quite challenging.

I completed three rounds of interviews — two remote video calls, first with a senior scientist and then with a managing scientist — and was subsequently invited for an onsite interview. Unfortunately, the organization of the onsite visit did not align with my expectations. Less than 24 hours before the interview, the schedule reshuffled, and the meeting was set in Natick during a January snowstorm, With a high risk of travel difficulties. In practice almost all of my conversations still were virtual, despite the travel. What added to the confusion was that the onsite location was neither the office I had applied to nor one where the team is primarily based. Even my host and another scientist had to travel from neighboring states to meet there, which made the arrangement feel inefficient. The HR interview was surprisingly strange. I was asked to discuss technical aspects of my research — essentially giving a brief technical overview — and to repeat information that was already included in my application. Although it mentioned that they already had all the info from my initial application form! many of the same questions were asked again. This interview felt unusual, as HR interviews are typically focused on administrative or cultural fit rather than technical evaluation

first + second rounds and then in person interview. They want to see how you connect your work with theirs. team is great and they are a pleasure to talk to.
