Zynga Software Engineer - Intern interview questions

Haven't received an offer yet, as still the process is going on. So selected "No" for the offer option here. Had applied through on-campus recruiting and got an email to schedule an interview. Was a basic HR interview with questions regarding my resume and projects I have done in the past and also on what I've been working on. Also, some basic managerial questions regarding how I manage stuff. Following were some of the questions: - Why Zynga? - Explaining some specific projects. - What was the most difficult challenge you faced in a project? - Given an ongoing project code base, how would you start with it? - What would be your focus for the future? - Situation: Given 3-4 days for you to convert a specification to be launched onto one of the games, how would you go with it?
