I did not get selected but I learned a lot of things

1st round consists of number series (find the missing one),aptitude and business english test. after that in the 2nd round you have to give an HR and Tech interview. It was quite tough. I was asked some puzzles . But they were quite easy. There were some questions from java and DBMS. Mostly he asked me from data structure. Everyone in the recruitment team was quite cool. One thing that impressed me the most is that they are super punctual, highly organised and super friendly. After 10 days I got a letter from them stating that I was selected.
