I had a 30 minute interview with the hiring manager/CSO. The interview was standard screening, but the interviewer was not very good at asking questions and seemed disinterested - every answer I gave was met with a short "okay" and moved on to the next questions quickly. When I asked what the day to day was like, the interviewer seemed annoyed and gave me very vague answers, which seemed like a warning sign that the management was very hands-off at the company. He didn't seem involved when asked about the next stages of the interview either.

Very unprofessional - after going through multiple interviews with positive responses after each, and fast movement through each round, I was ghosted with no communication at all from any of the hiring manager or recruitment team, even after several follow up emails.
