First phase of the interview was to make a computer game based on a spec received from HR. The graphics were all provided and I just had to write the code after I was done with that I sent it in to the HR person I was dealing with who got back to me to schedule the phone interviews. The second phase of the interview was over the phone with an HR woman who just asked basic HR screening questions before passing me on to the third and final phase. The third phase was a phone interview with two gentleman who asked questions on optimizing various features of a program including: Optimizing memory Optimizing execution speed Optimizing / preserving floating decimal calculations
