Game Closure Software Engineer In Game Team interview questions

After getting into contact, I was asked to complete a 7 day programming challenge. Part of the challenge was writing an essay about the development process. They're looking for someone experienced who already knows the technolgy, to be demonstrated by creating a polished game in the 7 days. Asking for 7 days of work is quite a lot, but they were clear from the beginning that they have high expectations.
