Interviewer was not pleasant to talk to. They were very aggressive and were not patient with me. We just did not connect and felt like I was wasting their time. They also sent me a couple of nasty emails after the interview.

Good place, nice interview process. Wasn't the right fit for me, but seemed a great place to work. It also seemed they have a few stages to the process, which is good for everyone to get to know each other.
