4 stages: debugging and implementation, behavioural, "codecraft" aka coding style, and system design The codecraft section was incredibly unclear. The interviewer told me it would focus on design then asked me to implement a simple 10-line function, leaving me unsure what to do for the next 40 min or even what the interview was testing. I asked questions to try to figure it out, but she mumbled so much I hardly understood anything she said even as I asked her to repeat it. I found out only after the interview was over that it was supposed to be about coding style/maintainability. I went in expecting the speed-run style algorithm-focused interview most companies do, so I skipped commenting and breaking up functions and that definitely hurt me in this round.
