Philips Software Engineer-II interview questions

I have a 6+ years of experience in C# .net and have attended a lot of interviews but hadn't seen any crappier than this. I was asked to attend the interview on a saturday, had to travel around 50 Kms from city and wait for 2 hours hence walked away. They called me again on monday, travelled the distance. The interviewer whose name i dont want mention here, thinks that by instantiating a value type Garbage collector is kicked. Asked around 4 basic questions about .Net and then asked me to leave. I am yet to know why he didn't like my answers
