Oh my god, they teach
you to ask those questions? I have been on the recieving end of those kinds of questions for a couple of years now (being young, and lacking qualifications & employment) and they are so incredibly boring to answer. I have actually answered these, more than once, 'Its not going to be one of those interviews, is it?'
I totally agree with your idea that candidates should be coerced into telling stories, but those questions make me and a few other people I know cringe with horror. Please, dont use them. Although the last one about how long youv'e spent in front of a computer is pretty cool, I remember this one time at university...
