Interview Preparation Tips

Interview preparation tips for other job seekers - Make the interview interactive, I got this input from another Senior. Before i went into the interview room the volunteers were telling all those who goes into Room No 1 is screwed. I was praying i don't get room no 1. But fortunately for me I got room no 1 because when the interviewer gave me the puzzle and handed over pen and paper he went back to relax his posture and when i explained i will fill the 5L Jar first, he immediately came forward to listen to me, at that moment i knew i got the job because i felt the previous candidates never made their interview interactive and that's why he went back to relax his posture.
