Addepar interview questions

First approached by recruiting for a brief 30 minute conversation. Passed on to hiring manager. Had one hour conversation and asked to continue conversation later in the day. Waited and followed up for over 3 days with little response before next phone interview was scheduled. After meeting with hiring manager, met with 2 other PMs in the group. One was incredibly rude and overly aggressive, never letting me finish my responses and more concerned about making me look bad. Brought on for a 3.5 hour on-site meeting after phone screens. Finally given a "case study" with very little parameters as "homework". It seems as if the company wanted me to use real artifacts that were shared with previous clients which is not something that should be done. The interviewers during the case study were once again hostile and rude and would yell out questions that would never be yelled out in a normal project meeting with informed stakeholders. That's the problem with having interviewees invent their own case study rather than the company setting the parameters. In the end, after almost 10 hours of interviews, where I took 2 days off of work and spent entire weekend making up a case study, I waited another 5 days for a response which was a form letter rejection. Glad I wasted my time
