Zynga interview questions

I applied online through Zynga's website to work at one of their studios NaturalMotion. A couple days later a recruiter reached out to me and asked to set up a time and date for an interview. On the day that the interview was supposed to happen, the recruiter nor anyone else from the company showed up to the interview and didn't give me any explanation as to why. I was sent the rejection letter 2 weeks later.

I passed the first stage. However i couldn't pass the technical stage.The questions were very technical and difficult.There were questions about syntactic sugars and core design patterns. I did not get an offer.
