The first interview was a very nice experience, the interviewer was prepared and created a relaxed atmosphere. At the second round I had a very short (10 minutes!) interview with the CTO- which was a bit strange and his questions were a bit judgy - and he promised to get back to me on Tuesday. Since then I've never heard back from them... This was a very unprofessional and unpleasant experience. I read the other similar review before my second round interview, but I thought it was probably a one-time occasion as everyone makes mistakes...
