Mechanize interview questions

Two rounds. First was a 20-30 min behavioral style "tell me about yourself" call. Second was 3 hour AI-assisted take home + 1 hour technical interview with an engineer about what you ended up building (only if it was good enough, else they'd reject after the take home w no call). The technical interview w the engineer was difficult, going through design decisions and tradeoffs you had to make during your take home, as well as exploring edge cases and how the system would behave given x and y actions from some user.

The process was very smooth: I had an intro call with one of their recruiters on Thursday where they asked about my background, then on Monday they gave me a technical take-home. I had 3 hours to create an app based on a spec, then another hour where they asked questions to make sure I understood it and wasn't just vibe-coding. There was a final call with the CEO right afterwards, then they made me offer and invited me to visit their office. I went in and talked with some of the team and they shared a couple of projects they're working on. Great people, although I ended up accepting a competing offer.
