They reached out to me (I was a passive candidate). At an informal meeting with a lead product manager they were very enthusiastic, so I agreed to complete a homework assignment. The homework assignment asked me to break apart the feature I'd be managing; specifically, drilling into metrics, developing a roadmap and spec'ing out a feature. They said "we love whiteboarding and brainstorming here". I spent about 2 hours on the homework to demonstrate my work, assuming they'd understand it was rough around the edges and that we'd work through details in the interview. Instead, I was surprised to get a direct, rude reply saying I had great ideas, but that my homework lacked details. My experience was very disappointing. The instructions for the assignment were not clear - I was told it was a brainstorming exercise, but it turns out they wanted a full PRD. Moreover, I find it unreasonable to expect a candidate to do 4+ hours of work before a first interview - especially a passive candidate. My takeaway was that they were much more interested in formality and process than creativity and vision. Not the culture for me!
