There are no stupid interview questions, only very clever answers. An increasing number of big companies (and small ones alike!) are using unconventional interview questions to gauge candidates' resourcefulness and thinking.
Briefcase in hand, the interviewee sits down. After a quarter of an hour, you begin to see the real person on the other side of the desk. You decide the time is ripe, sit back and drop the ultimate interview question: how many beers were consumed in the city this week? The answer to this question doesn't matter, you don't really care about the beer or mathematical prowess, however they do want to know that you can think on your feet and construct an answer with critical thinking. Could there be a better way?.
It's a craze that started with tech giants Apple and Google, whose interview stages became legendary. Now, more companies are jumping on the chance to see how candidates perform outside their comfort zones, and find out whether creativity and quick thinking are another one of the attributes they have to offer. If you're a recruiter thinking about using these questions, remember that there is a fine line between asking an out-of-the box question and something that may make interviewees think that you are insane -- tread carefully!
