⟩ If I have a Web application that I find is still running (via top/ps/whatever) but users are getting "connection refused" when trying to access it, how would I go about diagnosing the problem?
With the answer to that question, I get to hear about the interviewee's thought process, favorite diagnostic tools, and biases, as well as whether they really know how to solve problems. Getting the "right" answer isn't important, but it tells me about how the person thinks and how well they've familiarized themselves with the tools they use.
