My Box process ended up being pretty structured in a way I could plan around. It had four steps: a fullstack task interview that lasted about an hour, a culture interview for about thirty minutes, a system design interview for around an hour, and then a technical project retrospective interview for another hour.

The fullstack piece was the most hands-on part of the process, and then the later rounds focused more on how I thought about architecture and how I reflected on past work. Overall, it felt like each stage had its own purpose rather than repeating the same discussion.
