Multiple phone and Skype interviews, one onsite visit with multiple single interviews. The work and people were better than the interview process. Several last-minute reschedulings. Accommodated one rescheduled to Friday during a vacation, they canceled it that morning, then needed it that Saturday. So, gave up two days of vacation plans for one call. Arrived for onsite interview, overheard the interviewers weren't scheduled, so they improvised. Some presentation attendees paid no attention from the start. Presentation exercise's written guidance didn't match intention stated afterward; they suggested investing time in a second presentation. Was a finalist, interesting people and work, but was hesitant to accept an offer because the atypically chaotic interview process wasn't a good harbinger. Took another job.
