Saturn (NY) interview questions

First round: Standard recruiter call. Be prepared for 7 more rounds after that (yes, that's right. You will meet with 20% of their company). Second round: I was told directly by the recruiter that it would be a behavioral interview with the VP of Growth. It was not. It was a case study asking me to build out their growth strategy for a new product. I passed this portion and moved on to meet with the Product Managers. They were both great, and the questions were behavioral-based. Next round: I was asked to meet with an executive. I confirmed the interview and received a calendar hold via an automated scheduling system. The executive never showed up. When I emailed the recruiter after waiting on the Zoom meeting for 10 minutes, he proceeded to say that I "no-showed" the interview. This had already been rescheduled twice, so I assume the times got mixed up in their scheduling system. We rescheduled again, chalking it up to a technical error. I made it through that round. Next: I was to speak with another Co-Founder. He had to reschedule twice. During the final reschedule, he texted me directly, asking if we could "keep the time loose" for Friday and I should be expected to wait around all day to hear from him to confirm a time. Again, I am flexible and was willing to do this, assuming I would receive at least a few hours' notice. Apparently the expectation was that I sit at my desk waiting for his text to come through and be ready within a 10-minute turnaround to meet with him.... When he finally texted requesting we meet in 10 mins, I was in a meeting and stated I'd be ready within 45 mins. Never received a text back. I followed up with the recruiter directly and we confirmed a time for Monday instead. Monday comes - and I receive a canned rejection email 30 MINUTES before my final interview. I am not usually one to write reviews, but WOW. I have never experienced such unprofessionalism, poor business acumen, or lack of empathy for candidates. I can only imagine this is how they do business across most of their workstreams. Bullet dodged! Bless the poor soul who accepted this job.
