Zynga interview questions

This company not known for great experience. But contrary to that I had great experience with both HR and Engineers. Interview was conducted for Gaming service team. 2 online rounds where I was asked 1) Linkedlist 2)BST and 3)Distributed top K questions After that I was invited to Bangalore. First round was DS and Algo. Second interview conducted by Tech Director of Farmville 2 and he asked only one question of converting Roman Number to Decimal. Third round with Country Manager with usual questions. Lunch was there(heard good things about their lunch) with Fish, Chicken, WaterMelon, Papayya, Paneer, Chapati, Rassam etc Finally they offered me good compensation. ZYNGA is sinking ship but holds i) Cash of > $1 Billion and ii)Confidence of making big in Mobile mkt. They have one game "Dawns of Titans" waiting to be launched in 2016. I wish it changes the Fortune of Zynga(because Zynga known to reward employees with open hands). I had great experience with both Engineers and HR. But I felt very bad when I declined their offer as I was uncomfortable to shift to Banaglore
