I applied through a recruiter. The process took four weeks.
It's well described on their website, and my process went exactly through the stages from that scheme, which included an initial call, a take-home task, and more. The take-home task is an app that has many bugs which you need to fix within a limited amount of time to make it release-ready. During the take-home task discussion, they ask about your approach and the trade-offs you made. I didn't make it past this stage because I didn't do good enough refactoring.
What trade-offs did you make during the task?
