in reply to Perl Interviews

When I used to interview candidates for a SQL-related position, I would always ask the following:
If A has three rows and B has three rows then how many rows will the query 'Select * from A, B' return?

Most applicants got it wrong. The most common answer was six, but some people would say three. (The correct answer is nine.)

    Heh! Any SQL programmer who doesn't recognise a cartesian product would definitely be a liability on the team :)
