Puzzles are the latest fad in the job interview process that the corporate world has taken on recently. A candidate for JP Morgan or Microsoft is subjected to a humiliating process of being asked to solve a really weird puzzle that has absolutely nothing to do with their area of expertise. Many people who have been through this type of interview compare it to hazing.
There are many examples of such puzzles. There is an entire book and website industry dedicated to preparing you for this type of job interview. The one you see on the left is particularly popular, although there are many others (How to Ace the Brainteaser Interview, The return of the brainteaser interview: puzzles that challenge your logical thinking are back. , Brain Teasers, Book of Puzzles & Brain Teasers, etc.). This is an example of such a puzzle:
Three men and one woman find themselves on a deserted island. They only have two condoms between them. How can these 3 men have safe sex with the woman?
Believe me, people, I am not making this up. This is an actual question people are asked during actual job interviews. I am not even going to address the entire set of nasty, hateful assumptions that inform this so-called puzzle. Like, who said these men are necessarily interested in having sex with this woman, as opposed to with each other. Or, why would the woman want to have sex with all of them.
The main question here is what is the purpose of making this type of idiotic puzzle the central part of the job interview process. Contrary to what Microsoft and Wall Street companies claim, the goal of introducing puzzles into the job interview process is not to find the most creative thinker among your candidates. The real purpose is to find the most obedient, robot-like one. No self-respecting person with a degree from a respectable university will tolerate being asked stupid, irrelevant, and often offensive questions like "How many piano-tuners are there in New York?" or "How to design a spice-rack for a blind person?" The goal of such companies is precisely to weed out self-respecting, intelligent candidates. All they need is employees who would obey any humiliating task they are given without questioning their bosses on the legitimacy of the assignment.
