Very quick and aggressive process. Had multiple interviews in one day w/ multiple folks, sometimes having different interviews w/ the same folks more than once. One day was a "gauntlet-style" series of 3 interviews over a 4+ hour time slot. Final interview was a "culture-fit" interview w/ co-founder/CTO who seemed VERY aloof and was clearly working on other monitors while doing the interview, only halfway listening to my answers to his open-ended questions. Went through ALL of that, only to be ghosted after trying to get some simple feedback on a very canned rejection message.
