Apple Software Engineer interview questions

I had two interview sessions in the morning -- I am not a morning person. One question pertained to tree traversal so it was basic CS. Not difficult but if you haven't memorized the routine you have to work it out on the fly. A decent question. Another question pertained to keeping a table of custom table view cells fully updated with images. Again not difficult as I've done this. Before arriving I was asked to write an app similar to what they produce, which was not difficult and took 6 hours. I'll be putting that a variant thereof in the App Store. Very little phone screening was required before the interview was set up, which was irksome as it suggests a "culture fit" is what they're really trying to assess. I'm a dude but if they don't hire me, I hope they'll hire a female programmer to add some diversity. Areas for improvement for Apple: 1. Don't assume everyone is a morning person :) 2. Do a couple technical interviews over the phone beforehand like Google does.
