Zynga Software Developer interview questions

I was referred by an employee. I had already worked with most individuals at previous jobs. They flew me out. I spent about 4 hours doing 1:1 interviews with 4 individuals. (3 Senior Software Engineers and the Executive Producer). They asked standard Software Engineer interview questions that tested my in depth knowledge of the job. They also asked some teaser to understand how I approach a problem in a capacity I'm not familiar with.
