NDS Software Engineer interview questions

Written test, followed by two rounds of technical interviews and one round of hr interview, technical interviews also involved solving puzzles, not very tough though

I got the interview call through employee referral. Whole hiring process started from written test which includes aptitude and core java as the job profile for which I got the call was related to Java. I cleared the written test and got the result within 1 hour only. After that two technical round happened. Starting from OOPs concept interviewer asked questions in depth from core java. Most of the questions were from collections, string and exception handling. They asked some questions from design pattern as well. After clearing these two round, managerial round was there to clear. In that, interviewer screwed me like anything. He asked the reason for change and what are your future plans and questions like why NDS and many more questions. Somehow I managed to convince the interviewer by my words. Finally HR round happened. HR was very cool and asked very normal questions. All the rounds happened in one day. Within 1 week I got the the confirmation mail and offer letter as well. :)
