I gave the interview in October end and it comprise of three different rounds in total. I am mentioning the details below:

First Round: Written Round
The total time given for this round was 70 minutes. There were three different sections in this written test:
  • 10 English Questions

  • 30 Questions of Quant

  • 20 technical questions

  • The English questions were easy for me and the most difficult ones were the technical questions. It consisted of some tricky c/c++ questions and sql related questions. Watch out for the time as you may run short of that.

    Second Round: HR Interview
    The HR interview round consisted of two different parts.

    ===Casual HR Questions===

  • Third Round: Technical Round
    This was the most difficult round and I had a hard time answering the questions. I am mentioning some of the questions I remember:
  • Program to find duplicate number from array in minimum time complexity.

  • String Handling

  • WAP to show polymorphism

  • Overall, the interview was not too hard but it was not easy either. You must prepare well as the technical round can be a difficult one to crack.
