Hi this is Adriano. I wanted to apologize, it was not my intention to conduct the interview in that way. No excuse for being late or flippant at the beginning. Sorry about that. I know interviewing can be stressful and I am sure that behavior can add to it. Re: the point on the introduction, that is something we do slightly differently. Our technical interviews only test technical abilities and do not touch on fit (which is assessed in different parts of the interview process). Hence, the decision to move on to the next phase is made solely on the solution to the technical problem (rather than fit) as the later stages of the interviewing process give us an opportunity to dive deeper with candidates. Internally we also talked about tweaking some of our process to make that clear. Re: my personal performance, that is something I will work on.
