Asking puzzles in interview is stupid - agree / disagree?
In most of the tech-interviews in India, interviewers tend to ask puzzles, brain-teasers and trick-questions. I'm not sure if this really works and what purpose it solves, but the trend has continued for a long time now. I personally used to ask brain-teasers when people's resume had nothing interesting or worth grabbing attention - but I gave up on that practice because it started to look stupid. Apart from making the Interviewer smarter than the candidate (because he already knows the solution to the puzzle), the whole puzzle solving process proves nothing.
Some think that it gives an overview of the 'approach' & creative thinking a candidate applies to solving the problem or puzzle. It may, but only when the Interviewer is actively engaged in checking out what steps the candidate is happening. In the interviews that I attended, the interviewer would draw or write the puzzle statement on a sheet of paper and then simply walk out of the room to grab a cup of coffee or tea and come back after 10-15 minutes only to check whether I've arrived at the correct solution.
In real world, collaborative problem solving is more difficult when you've 10 different views on the issue at hand. The approach is 180 degrees different from what a candidate can execute in a time-bound interview.
So - do you think the tradition of asking puzzles in interviewes should be abandoned? Hit agree/disagree and express your opinion via comments below.
