This was one of the longest and most unprofessional interview experiences I've encountered. 8 interviews, 7 of them were roughly 1 hour in length. 2 days had 3 interviews on each day, 1 in the morning and 2 in the afternoon which took up basically the entire day to be prepared/ready for. 1 out of 8 interviewers no showed. 2 / 8 interviewers were 5m+ late to the interview with no warning. They offered a "feedback" call after passing on me, however no-showed the call even after coordinating a date and time block. Basically zero respect for the candidates time. During the interview process for the case study they used their direct product that the position was applying for as the use-case, which is generally a no-no from my experience. There were several other red flags about company culture and process.
