The best engineering interview question I've ever gotten
Author of the interview question here. I came up with the idea after working at the company for a couple months and realizing that the skill of "diving into an unfamiliar area of the code and quickly figuring it out" was very important for us. Database codebases are large and complex -- so much so that almost every new feature you work on for the first year or so feels a lot like doing the question.Over the years of evaluating with it, we learned a lot about its quirks (both false positives and false negatives). At one point, someone got so frustrated that they threw their laptop on the floor. Happy to answer any questions about it!
