instead of asking them stupid, verbatim-recall questions, i give them a problem and ask them how they would solve it. i.e., "a customer reports his website is running too slow. describe how you would identify and solve the problem." it's a good sign when they start asking you follow-up questions, like "is it load balanced? is there a database?". it's a bad sign when they say, "just restart the server".
I got asked "what happens when you hit return in the browser?" After I had traced from the keyboard driver through libraries and runtimes to the browser event system, then back down thru the network layers to sockets, then thru IP events to land a packet on the remote router, they called a halt. Apparently nobody had actually answered the question before. IMO Its a good exercise for problem-solving, and plumbs experi…
But if anyone thinks that either of these questions is testing "critical thinking skills", or "problem solving", then I would like to hear in what way. Both of those seem to me to be pretty much archetypal "verbatim-recall questions".
Experience and exposure and education and ability to brute-force recall all of the above is valuable. But it's pretty much the exact opposite of what beachstartup said (s)he was testing, and there is zero "problem solving" in the "what happens when you hit return in a browser" question.
I'm a little bewildered how anyone could confuse these diametrically opposed aptitudes.
