Questions Asked

  1. Online Technical Test (90 minutes)
    It was an MCQ Test divided into many sections. Every section has a separate time limit and after submitting each section you would be proceeded to the next section. There were questions related to Aptitude (Qualitative and Quantitative), English (Reading Comprehension and fill in the blanks), Technical (C, C++, OOPS, Data Structures), and a coding round. In the coding round, there were two questions. My questions were first to find the sum of digits of a number and the other one was to reverse the words of a sentence. My friends had questions like checking whether a series is in AP(Arithmetic Progression) or HP (Harmonic Progression), check whether the number is Armstrong or not, Max product pair in an array, etc.
    I was able to clear the round. The interview was scheduled for the next day. Around 20-30 students were selected among 400 who gave the test. Overall, the difficulty level of this round was easy to medium.
  2. Interview Round (20-25 mins)
    Two people were sitting in the cabin. They had a copy of my resume which was taken from me earlier. Then one person asked me to introduce myself. After that, they asked me the following questions -

    • We have banking data with daily transactions. Which type of database would you prefer to store the data - SQL or NOSQ? and why?
    • Advantages of NOSQL.
    • Write a program to Find the frequency of elements in an array. (I used the unordered map in C++ for storing the frequency of elements)
    • Can you optimize your approach
    • Do you know about the internal working of the unordered map in C++?
    • Asked me about one of my projects on my resume.

    • Tell me about your family background.
    • Do you have any questions?
    3. I was not able to clear this round as I was from a C++ background and the interviewer was seeking from a Java background or someone ready to join QA.
