Long and verbose. Didn't seem to yield better results based on length. Ultimately job was offered to another candidate that was internal. Given this, would nice to have known earlier.

Extremely long process. Takes time to get on folks calendars. Multiple interviews in the same day and multiple interviewers in the same interview. The organization is difficult to get into and the interview process is how they manage it. HR is slow to respond even if they are very much interested in you.
