Interviewer was pleasant and helpful. Interview was about 2.5 hours long. First part was usual "getting to know you" type stuff, and I was asked to talk about a project I had done. The rest was 3 technical questions in ascending order of complexity.

1. I was asked about the most efficient way of sorting numbers within a certain way. The catch was to use extra space and create a histogram to optimize time.

2. Given a piece of code - to tell what it does (I was given code that sorts numbers by mod 4)

3. Mathematically define the distance of the car, given a picture from a camera behind it. What happens when you change the angle of the camera? The height?
