Interview Preparation Tips

Round: Other Interview
Experience: One year since I took the interview, so no idea exactly what questions they asked. But I was asked to write the code on paper in front of him and was asked to debug it. Some puzzles and aptitude questions along with other basic coding questions. It was great that the guy was interactive and started asking about my projects and college life.
Btw the answer to the logical question is: I should say " you will shoot me". Paradoxical.
Tips: Feel free to ask anything that you would like to know from them. Also frankly say that you don't know a certain topic if you have no clue what it is about. They don't like people wasting their time.

Round: HR Interview
Experience: This was not exactly a technical interview. He asked me to write a code to find the day of week when a certain date in any year of the calendar is given. I answered it and then he starting asking general questions as to why do u want to join the company, etc.
I gave answers to most of them convincingly. But I kept him engaged by explaining my life at college, the extra curriculars I did at college. Also I asked him about his experience as a software engineer. I asked him to reflect upon his career and how I should approach about my career.
Tips: The best part about HR interviews is they expect you to ask them lots and lots of questions. The more they are engaged, the more are your chances of impressing and getting selected. And more importantly, ask the interviewer about his experience with the present firm. This also works with my manager when ever he has a one on one with me :P
Cheers and all the best.

Interview Preparation Tips

Interview preparation tips for other job seekers - Not at all worthy experience. Such a huge organisation and HR people they don't know what does a offer mean to a new Candidate. You are not going to the market to buy stuff. You have to earn your candidate and same for candidate as well. Both have to mutually understand each other needs. If you cannot make an offer to the person then kindly do not waste neither your time and nor theirs. And if you have to hire real talent then expand your budget, stop bargaining.
