Indiabix is good for refreshing your basics.
2) Technical : 22 questions in 30 Mins. Computer Science typical questions basics from CN,OS,DS and Algorithms, DBMS .C /C++ output questions. Easy level.
3) OOP concept test: 8 questions in 15 minutes. Needs to choose either C++ or Java. Easy and typical
Indiabix and Geeksforgeeks are good source to revise.
I cleared this round.
More you score here, better the chances for you. They might make list of interviewees based on marks you get on 1st round.Though it is not official.
