Recruiter call, followed by one technical interview, followed by 4 rounds of virtual on-site interview (3 technical, 1 behavioral). During the on-site, the interviewer was 25 minutes late to the first round. I only got the remaining 35 minutes to complete the technical question (which I did). The other rounds went smoothly as well. After the on-site, Verkada emailed and asked to do the first round again with a different interviewer since it was "short". This was very unprofessional since it was their interviewer who was late, and by good practice, they should not have scheduled another round. Regardless, I scheduled another interview with them for the next day, which then they pushed back another day. Then a couple hours before the interview they emailed and cancelled it, saying they hired somebody else. This was an extremely unprofessional way of dealing with a candidate, and I would definitely deter anyone from interviewing with them.
