The first is a skills test, 10 questions about Windows, 10 about Mac. There is a typing test and you have to get 30 WPM. There is then a normal interview, and later a 1 hour long 2nd interview that is one on one. The one on one interview tests your ability to work on both a PC and a Mac. Use keyboard shortcuts to cut and paste is one of the questions. The interview also has a test where you have to guess an item in the room and you have 10 seconds to narrow it down to the item and then guess what it is. It tests your ability to troubleshoot.
