Dandy RESCINDED their signed offer to me AFTER I had left my previous job and 2 days BEFORE starting. Overall, the interview process is fairly standard. I liked the team that I interviewed with and was excited to join.

Excellent. Well-crafted. One of the Dandy core values is moving at Speed. You can feel this in the interview process. They interview quickly and then quickly make a decision (yes/no). No beating around the bush. It was refreshing. They moved deliberately, not carelessly, in the quick interview process. You have several interviews. The primary ones I remember were: coding challenge (get all unit tests to pass - important!), data modeling and systems architecture, past project deep dive, and review your previous jobs and why you were hired, what did you accomplish, what could you have done better, and why did you leave. Dandy has a high bar. It worked out for me.
