Applied through their online portal. Two months later I was invited for an interview at their headquarters located in Boston. First round: 2 back-to-back interviews, 45 minutes each (10 minutes of FIT questions, 30 minutes on the case, 5 minutes of Q&A). The FIT questions were pretty straight forward as were the cases themselves. That said, interpreting and generating insights from the charts/data/graphs was probably the hardest part, given the time constraints, pressure etc. Everyone at the company was very professional and kind. All in all, a pleasant experience, however, I was disappointed that I did not receive any post-interview feedback.
