They saw an application that I wrote on my website and offered me an internship. I worked on some of their smaller profile projects for a year until they offered me a full-time job.

I don't remember the questions being very difficult, although it was a while ago. I think at Apple, they are really looking for something different about each person. For me, they saw an app I wrote and released when I was 13, and they thought I might be useful. For others, it may be different.

You have 100 coins laying flat on a table, each with a head side and a tail side. 10 of them are heads up, and 90 are tails up. You can't feel, see, or in any other way find out which side is up. Split the coins into two piles such that there are the same number of heads in each pile.
