1st Round was written(Technical/aptitude) round. It was followed by 3 rounds of personal interviews.

In 1st technical interview I was asked questions data structures, oops concepts, algorithms and puzzles. 2nd round was managerial round where I was asked one puzzle by the interviewer and told if I could solve the puzzle then he would send me to the final round.

I solved the puzzle and I was asked to wait for final round. I waited for 2 hrs and it was late in the evening and then the HR people were in a hurry to leave to home so they just took their bags and left. They didn't take final round for me. The recruitment team were inexperience and had a pathetic management.

Basic questions data structure,oops,algorithms,java and dbms
