GHOSTED. Did 3 rounds and a case study (presented case study in front of a panel of 3 people). The case study took multiple days of prep (while employed full-time). Received nothing but positive feedback after each round. I even sent a follow-up email to managers and recruiters I had worked with - no response. Do not waste your time - inconsiderate HR and managers indicate a bad culture.

Easy interview process and generally nice people. Asked plenty of questions and they had good answers. There was a small case study that I had to do ahead of time. I heard back after the first round of interviews with an offer.
