First two interviews were with an SVP and Director of Product and they were good, easy to talk to and not technical. After that they gave a week long take home project. I usually don't do interview projects just based on principle but I decided to do it this one time since I liked the people I had interviewed with and was genuinely interested in the role. They gave a week but I have a full time job and I'm interviewing with multiple companies so I gave myself an 8 hour limit on this project. The assignment was rather vague and suggested mockups to be included which of course I did. When it came time to present, they were incredibly nit picky on very small details of the mockup wanting to go deep into the data modeling on a granular level - I also didn't have enough information from them to be able to model the data and then when asking for more information, they ended the question and moved on. I was expecting much more high level questions about my process, the persona I built, more big picture since that was the project assigned. The level of detail they suddenly wanted was not something I could have prepared for given the vagueness of the brief and the time I had invested in the take home project. They clearly were not happy about this then got very quiet and I could tell they were messaging each other during the remainder of my presentation. At the end when I asked for additional questions or feedback, they said "No, thanks, bye" and ended the call. It was so weird and totally turned me off to the position. The next day I got a generic system generated email saying they rejected me. Read some other reviews from the last week of others who had similar experience. Definitely dodged a bullet and would not have been happy there.

Hiring manager is the first call instead of HR. 5 interview rounds including a case study which is requested in advance of presenting/scheduling the case study. There was very quick responses from the hiring manager however no feedback was allowed to be shared after any rounds or rejection.
