Heavy on technical topics. I was asked to write a simple algorithm. A lot of behavioral questions. One of the three interviewers (developer) was on the phone most of the time, it seemed like he was watching youtube in a landscape mode. If it's not worth your time, then why would you attend the interview? CTO was very interesting to talk to though. Unfortunately, the overall process was very disorganized, I only got one reply to my email with the invitation to the in-person interview. No other/futher follow-ups. At all.
