That's a great point! We didn't actually think of this question as much of a "measure" (and I think the blog post alludes to this as well with a "Fizz Buzz" analogy). We thought of it more like a filter — if you couldn't pass, then you _may_ not be adept at navigating through a database-y codebase at the pace that was necessary (at that time) for the work we did. We had other questions (which I won't spoil) that tested more complex system-design skills, without having to implement them within an existing codebase. We felt this provided clear independent signals (ability to "hack" within a codebase and ability to reason through complex system design) vs. conflating the two. As the team grew, and we needed folks who were much better at one or the other, this helped us round out the team with folks who excelled at either skill.
