Zynga interview questions

I was asked to make a presentation on Increasing DAU and MAU for the organization. As Zynga was one of the companies I really wanted to work for, I put in my heart and soul into this exercise. I downloaded their game and played it continuously for a week to reach up to level 17!! So much time and effort, just to understand all their offerings and come out with a really good solution. I did come out with really good solutions, which got me through to the Interview round. Here, I was interviewed by a guy, who had not even looked at my assignment! He was clueless.. He did not know what to interview me on. His communication skills were horrible and he took so much time to clarify the first question! I really felt cheated on my time, effort and commitment to get into Zynga. They should have at least brought in the Hiring Manager who could have been much more serious. Or even someone who has gone through my assignment and could have a meaningful discussion. Extremely disappointed with Zynga..

Technical Round on Algorithm. The complete process is unprofessional, Initially, the Interviewer joined the call late, No Explanation and Introduction (Not even Name), Who he is, what he is expecting from this round, He directly put the Question related to the Dynamic programming problem (with No proper explanation), I was well prepared with Dynamic programming problems and possible solutions, I approach the Solution, which is pretty clear and he asked to think solution and code in 20 mins. But he came with his solution in mind, and I feel he didn't understand the Solution proposed by me, Even the outcome was correct. Really worst experience ever. My Mistake I Applied Here. I will never apply and never recommand anyone here.
