I've done a lot of interviewing recently for roughly mid-level DBAs, and the quality of the applicants has been so varied. 90% of them failed even the most basic questions on the the technical test (e.g. what are the recovery models called). In addition we've had some blatant cheats (one of which had a friend with him for the telephone interview who was feeding him the answers). Why would you want to get a job you literally have no chance of being able to do?
That said, I've never been a big fan of things like the FizzBuzz question for hiring DBAs, because although I can pick my way through it, I don't (personally) think it's all that pertinent to the work we do. (Obviously development-aligned DBAs would need to know this.) Being really solid on backups, restores, security, configuration, etc. seems much more important to me.
I can return the date with T-SQL though :-D.
