The interview process at Brex is fairly standard - a coding screen followed by an onsite with two coding assessments, design, debugging, and a values interview. Of these, the debugging session was particularly refreshing as I was given a small codebase with some latent errors that I had to find and fix.

Brex gave me a positive interview experience that focused upon the practical demands of the role — i.e., stuff I would actually do on the job. The 3-hour frontend assignment was fun. It was challenging without being tricky, and I could make my own framework choices and work in my own editor, so it felt comfortable. The scope of the assignment wasn't unrealistic, but I doubt many people finish it in its entirety, so don’t let that dress you out. I'd take this kind of interview any day over Leetcode-style problems. My only gripes were that I could've really used a 5-minute break during the 3-hour coding period. (I could've taken one, but it would've come out of my coding time.) Perhaps they should require a 5 minute break at the midpoint? Also, for the more senior engineering roles, I think it would be wise for them to probe a bit more for leadership skills. The values interview focused entirely on whether I'd be a good teammate versus an effective leader.
