How logical are you ?
Here's 9 tricky job interview questions, some of which are designed just to check your logic:
Q. There are nine balls, one of which is lighter. How would you find the lighter ball using the lowest number of weighs ?
A. Divide the balls into sets of three and weigh all three sets. One of those sets will be lighter, so now you know it's one of those three. In the second step, you weigh two of the three balls. If one weighs less, you now that's the light ball. If they're equal, you know it's the ball you didn't weigh. That's it - done in two steps!

Q. If we were playing Russian roulette and had one bullet, and I randomly spun the chamber and fired but nothing happened, would you rather fire the gun again or respin the chamber and then fire on your turn ?
