Thank you for the answers and for the advise too..I take it for sure.

Koen, I have told them the answers. The answers I told them are not exactly like you told but some how I managed to tell them correctly. But they were starring at me like I was wrong. So I got to doubt myself. So that's why I posted these questions in here to clarify myself. And more over I got selected for the position. 🙂

I really thank and appreciate you for your time that you took to reply my questions (stupid, may be :crazy:)
