It was a long interview process: recruiter call, take home, phone screen (system design) and then the final rounds: take home review + coding challenge, another system design, and three behaviorals. There seemed to be a big emphasis on ambiguity because a lot of questions they asked were very open ended so it was a bit hard to know where to focus. The first screening was a typical "how would you build x" system design, but the second system design question was a different format and I was unprepared for it. Even though it was a very long process and I was very tired by the end of it, everyone seemed genuinely nice to work with.

Recruiter Screen followed with an option for a 1hr live coding or a take home challenge Take home challenge was fine but requirements and guidelines should be more concrete. I have no idea what their version of "production-ready" code looks like and everyone is looking to give the bare minimum since you have 3 more coding rounds. Do you want tests? Do you want error handling? What should be the bare minimum when I'm just scaffolding a TODO App that should "only take 2-3 hours"? You're not FAANG, stop putting candidates through 6 rounds to make a decision.
