Had a brief call with a technical recruiter and moved to the next round, which was a technical screening. The question was straightforward and simple compared to some other interviews I've had.

I recommend an approach that used simple iteration to update state to solve the problem. However, the interviewer said that wouldn't work, so I struggled to extract his implementation. Afterward, I went back and verified that my original solution did, in fact, solve the same problem and was less verbose.

I'm not sure how to offer advice to other candidates, as it seems thinking out loud may cost you.
