Confusing and long; the communication was very poor during the interview. Try not to get an interview after 4 pm on a weekday – it is clear they only want to go home. The interviewer was unclear in what he wanted me to do. The interview only focused on programming skills; no other questions were asked, not even past work history. It felt very informal, and I doubt the interviewer actually cared about personality for the work environment, only technical skill. The coding questions are Google-level of difficulty.
