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.

Many rounds of interviews with a very time-consuming project in which I was required to design a product feature that was actually on their roadmap. The hiring manager's boss attended the case study and abruptly, with no notice, changed the structure of the interview on the fly and demanded a live data-modelling exercise instead of allowing me to present my prepared case study. Up until that point, the hiring manager had expressed concerns re: seniority but seemed to be open to hiring for potential. Unfortunately it appeared his manager did not agree and was cold, rude, and dismissive in the case study. Fortunately I think it says enough about the culture of the team I would have been joining to allow me to feel fortunate I didn't leave my current role.
