Zynga interview questions

Literally the worst interview experience ever. The HR called and did a screening. Nothing too difficult here as most of the questions were about your previous experience. Then the HR scheduled a time for the interview with hiring manager, and the hiring manager stood me up!!!! Few days later the HR sent me an email apologizing and said the schedule didn't appear on hiring manager's calendar and had me rescheduled. I waited til appointed time and 5 minutes after the scheduled time, I received another email from HR saying the hiring manager couldn't make it to the interview. Totally disrespectful!!! I've interviewed with a lot of big and smaller companies and I've never been treated this way. Zynga, if this is how you treat a candidate, you are never gonna attract any talent to your company.
