I underwent 4 rounds of interview starting with HR and ending with the Senior VP. I felt the interview weather got hot, hotter and hottest as I progressed one after the other rounds. The last interview was the best learning experience for in my interview life. When i finished my last interview with Senior VP I felt I was not through it and I will not get the offer. He was testing my mettle and how tough I can go in certain situations . Even though i felt i didn't do that well I got an extraordinary confidence from this interview that I can do any other interview with ease. He tested my patience with utmost dignity. Till I got an offer letter I thought I didn't do the interview well. I hope am going to learn a lot working with him. my first impression about my future boss is, he is tough and teaches you a lot if you know what he really wants from you.
