We were interviewing a new admin for the sysadmin/maintenance team and her answers to "how would you solve this problem?" were "Open that file and check that these variables are set and, if not, set them". One of the more jerkish people there went down the rabbit hole of "How are you going to edit that file? What if you don't have vim? Okay, what if you don't have emacs? Nano is gone too" leading to the response that made us hire her: "Well, in that case the system is probably completely hosed and we need to stop configuring things and focus on recovery. But I think you are looking for me to tell you a sequence of commands that involve cat. If you give me five minutes I can check stack overflow and get back to you with those"
Which I personally think should be the response for stuff like that. Understand there is an alternative and a way to resolve the corner cases and know how to get that info if needed.
