Round-1 (Online Test)

The first round comprised of 50 MCQ Questions (Test Duration: 1 hour) including:

  1. English
  2. Reasoning
  3. Quantitative
  4. Technical

English, Reasoning and Quantitative part was relatively easy and if you have had a regular practice of attempting such questions then it wouldn’t be a problem for you as they were not tricky and only tested your basics.

Suggestion: I would suggest to do practice from books by Arun Sharma.

Technical part covered questions from Computer Networks, Operating Systems, Data Structures and DBMS.

Suggestion: I would suggest to do quizzes and read articles from GeeksforGeeks to get in touch with all concepts of OS, DBMS, CN.


  • Keep your head straight and never panic.
  • While the time may seem less for the number of questions always focus on the question rather than the fear of spoiling your test.

Round-2 (Technical Interview)

  1. Given an array where every element occurs two times, except one element which occurs only once. Find the element that occurs once. ( I gave two approaches to the question, first keeping a frequency array and storing the number of times an element occurs in it, the second approach was based XOR.
  2. Given a string, check if it is palindrome or not. (
  3. Given a string, the task is to find the frequency of each word in a string. (
