Downvoted because there was no chance to prove myself. There are a minimum of 3 interviews plus a conversation with the CEO if you make it passed all of them. Both conversations I had were pleasant, so I thought. In hindsight, what I had interpreted as a "chill" attitude from my second interviewer I believe now was that he had already made up his mind. No matter what I said, after I said it there was a pause, and he would try to relate to what I said instead of keeping any kind of pace in the conversation.

First, the interviewer forgot the day that he had an interview with me. And than, he was not prepared during the interview. He forgot how to solve the problem, and when I googled it he remembered. Even though he knew that I was a junior developer, he said they want more mid level engineer. Awkward!
