People in the interview was very nice. It was mostly like tech chat. They asked me very detailed questions related to my current job. I believe they liked what I was doing but I think I couldn't answer some questions how they wanted, I realized that in the interview. I went to so deep instead of explaining simply. Also, there was one tech question that I could not understand properly and I hurried up because the interview time was ending. In the end, I couldn't be proceed for the next step. As I understood, they expect you not to make any mistake.
To sum up, it was good experience because of the interviewers, it doesn't make them bad because they didn't choose me.
