Try this out and then post your answers - but don't post an explanation. We'll see how people do then explain it later.

Let's say you have 4 cards and the cards are supposed to obey the following rule: If there is a vowel on one side then there is an even number on the other side.

You only want to turn over as many cards as you have to as they are very large and weigh a lot. Which cards do you turn over to see if they obey the rule?

Again don't explain your reasons or give the answer away.

We don't know what our limits are, so to start something with the idea of being limited actually ends up limiting us.

If you put the cards on a conveyor belt, they will not take off.

if the cards are placed on a conveyor belt, no matter the speed the conveyor belt achieves, for a moment at least, the cards will be airborne which means they will have to at some point have taken off.

Is this a 'how smart are you'? Or more of a 'how good are you at propositional calculus'?

Smart is a pretty subjective word.

I think it's just a matter of thinking about the question.  First look for me was a jump to what I thought was an obvious conclusion.  Had to read it over a few times.

Here's a fun interview question:

Don't post up how you did it, just the number of drops in worst case scenario. If you want, you can easily google the answer, but that's way less fun.

You're standing in front of a 100 story building with two identical bowling balls. You've been tasked with testing the bowling balls' resilience. The building has a stairwell with a window at each story from which you can (conveniently) drop bowling balls.

To test the bowling balls you need to find the first floor at which they break. It might be the 100th floor or it might be the 50th floor, but if it breaks somewhere in the middle you know it will break at every floor above.

Devise an algorithm which guarantees you'll find the first floor at which one of your bowling balls will break. Post up the number for the max number you would have to do in the worst case.
