Following my referral from a recruiter, I had a 1:1 phone screen with a representative from HR, followed by a take-home assignment, which should take a few hours. Had I advanced past that stage, there would have been a group technical interview, followed by a live-coding session, and then a couple interviews with the VP and co-founder. While the overall experience was worthwhile, I can't say it was positive with respect to the take-home assignment. Though the exercise was fairly straightforward (at least I thought so), it does take several hours, and you will be provided with absolutely no feedback if your solution does not pass their tests, just a pass/fail from HR. This will no doubt leave a sour taste if you're the type who appreciates understanding why/how their architecture fails, and values learning from their mistakes. Overall, I can only recommend interviewing here if you feel very strongly about the role on the table; otherwise it may not be worth your time.
