Got fast-tracked to onsite with a referral. The process consisted of four technical interviews and one behavioral interview during a "superday." The recruiter was very nice, but in the end, I didn't receive an offer.

Got very strange questions that didn't decompose down to data structures well, with many edge cases.

Did this interview remotely. Some interviewers turned off their mic and didn't appear to listen at all. One showed up thinking it was a technical interview when it was behavioral.
