There were 3 technical rounds and 1 HR round. In general technical rounds include questions based on algorithms, data structures of medium to average difficulty level. Questions were majorly on linked list, arrays and strings. Then there were questions on DBMS and OOPS. Asked to design a database for an e-commerce company and then asked to write some SQL commands. In the first technical round interviewer asked 2-3 puzzles in the starting to make me comfortable with the environment.
