Programming exercise was good- you had 1:15 hr in XCode to write a simple iOS application with data persistence, implement a shake motion gesture, localize it into french and spanish, and ensure the UI resized correctly. Then you had to write the test cases for your app. All told if you knew what you were doing you should have the basics done in under an hour. From there you can spend the rest of your time making the UI pretty.
