1. Most IQ tests are Bullshit 2. We all know what happened to the company famous for " Who moved mount fuji" 3. Math Puzzles are good if they are of the IMO level- but these things need a lot of concentration and joy to solve- Not under stress interview conditions. 4. Expecting someone to show brilliance by solving a math puzzle in under ten twenty minutes is a lot like a public willy wagging competition 5.Even more disgusting is the semi dumb questions at Mckinsey inerviews like - "Estimate the number of mineral water bottles in London" 6. 7.In 'Jobs', Walter Issacson says Steve was never into much of these puzzles- I can understand the reason. 8. ' I think a lot of what people call intelligence just boils down to curiosity'-(great quote from an inspirational friend-http://www.flickr.com/photos/elizabethbw/8373942339/) 9. People who ask these kind of puzzles end up creating a lot of CPU without any GPU. Very Little beauty. Very Little love. Disclosure- Im a member of Mensa Inernational. No Offense meant.
