Do You Have Any Questions?

The ghastly interview question used to be "See this pen? Sell it to me?", but that's now out of fashion. The hot new torture is apparently to ask interviewees why manhole covers are round.

Lucky I'm self-employed, because I'd never get the job. The answer they're looking for is that with a square cover there's a risk of it falling through and crushing a hapless sewer worker (and their lives are bad enough already).

I would have said "Because manholes are round".
