Got the initial interview from on campus recruitment and got the superday offer the day after. superday was a week after, and contains 4 rounds, even one was with VP. Mostly the questions are based on Java concept like what's garbage collection? what does "volatile" keyword do?what's the difference between C++ and Java? what's the difference between Java abstract class and interface? Also contains question regarding design pattern, I get several question about singleton pattern. Just a few programming work given Java. No brain teasers, but the interview question are creative. Generally not very hard, interviewers are very nice. A very good experience.
