The interview lasted a whole day and was very grueling. It felt to me as though the questions were really aimed at recent Comp. Sci. grads. I didn't feel that the process truly reflected the sort of work that I had been doing and the kind of work that I was hoping to get hired to do.

We did touch on some questions specific to the task, but these came at the end of the day and were almost perfunctory in comparison to the computer science-type questions I got earlier in the day.

Most unexpected was what I considered my favorite design pattern. I don't have a favorite; I just use whatever is best for the task!
