Interview Preparation Tips

Round: Test
Experience: The aptitude questions are very basic level and doesn't take more than 20 min. Coding question is also very easy if you get the basics of C language right.
Tips: Practice writing online coding tests as passing all the test cases is the main part where we'll have a problem. Although you get the code right, concentrate on the various test cases they may check and put your variables and output accordingly. For example, our test cases involved large values so I have to choose a double int data type instead to int. This came out of trail and error as we donot know the test case.
Duration: 75 minutes
Total Questions: 31

Round: HR Interview
Experience: Questions like Why into software from Mech? will be asked.
Tips: Be talkative!! Answer all the questions confidently. Slight preparation will help, but donot reproduce exactly what you have prepared.
