One way video interview with some intro questions about yourself and then some product evaluation and market sizing questions. They give you a short amount of time to read/listen to each question and two minutes to answer

4 rounds; the first being by far the hardest IMO- very non traditional case. Every stage of the interview process is enjoyable, interesting, and everyone I spoke to clearly actually loved their job and team. Super, super heavy emphasis on coming up with on the spot answers and personality fit. The case was challenging but interesting if you like diagnostics; it is necessary to have practice making slides beforehand. Interviewers were kind and welcoming; I never felt lost or unprepared as they outline the whole process very transparently on their website and clearly communicate what they are looking for in each interview. Be very familiar with their website, and expect to be asked extremely random questions
