It took about a month, give or take a week, to schedule the interviews. They had difficulty finding interviewers with my programming language of choice, but I told them I could do another, which helped secure interviews.

The majority of the interviewers were great, social, and overall helpful. One interviewer was rather quiet and presented a lengthy problem. Another engineer was assigned to ask me an architecture/design-related problem for a platform I'm not too familiar with. That engineer believed there was a mix-up between him and another interviewer. An attempt was made to schedule another interview to compensate for the mix-up, but unfortunately, that position was put on a temporary hold, or so I was told.

This is a neutral review because there were a few issues during the process, but the interviewers were pretty good at keeping the interviews comfortable.
