Initially a written test was based on aptitude. In that 30 questions were to be answered in 15 minutes approximately. Those were very easy questions and you only need speed and some common sense to clear the round. The second written test was a technical test. Questions of C/C++ regarding void pointers, pointers, structures, etc were asked. Refer C++ section of Geeksforgeeks.org and you will clear this round. The other round was face to face interview with a panel of 2. They asked questions that were asked in the written test and also asked some puzzles. You crack the puzzles and you will be through this round. The next is a 1:1 HR interview. Be confident and frank. Accept your mistakes and you will be placed. Wish you the best of your luck.

The company had campus drive in our college. After PPT there was an aptitude and technical test which was mostly having C/C++ questions. I cleared first round so there was interview the same day at our campus.
