The first interview with Lutron was a 60-minute video interview. The interview consisted of two problems: 1) What will this code print? It is question seeing if you can tell the difference between pass-by-value and pass-by-reference. 2) Create a Rectangle class in whatever language you wish. The point of this problem is to show that you can make a class. Then I was asked to include a undo function. I then had to add functionality to the class in order to track the state of the class. Next, I was ask about how would do inheritance so that there could be other shapes. Finally, I was asked what would need to change in order to allow an undo function to undo the last modified shape, not just an undo relative to one function.
