Had an initial call which was straightforward and went well. Then I had an in-person interview at the Waltham location and it was relatively easy although long. I meet with the entire team (5 or 6 people) split into 3 parts (2 ppl each). It was mostly me talking all of the time, questions were not too hard and they were kind of repetitive. The interview was like 2 hours long and I got an offer very soon after. Overall a good experience.
