I was given a similar interview problem and thought it was one of the better interviews I've had. In my case the interviewer pulled up a web app and said this particular page is loading too slow, how would you approach the problem? We went from opening dev tools to look at the requests driving the page all the way through database optimizations and every layer in between.

This kind of interview didn't feel like a gotcha and was much much closer to real world work than the toy and/or algorithm problems that I have encountered. More companies should adopt these types of interview approaches.
