I had one interview, where the people were asking detailed questions about how a particular tool worked. i.e. when this error occurs in the DB, how do you fix it... I am a SW dev, who likes to work with DB not a DB admin. Had they asked me 'When you get a code dump how do you debug it?' I would have had an answer. As in all interviews they asked me if I had any questions. Each question I asked their answer was that my question was not relevant. I told HR I do not want the job, not that I expected an offer.
