Around 250 members were shortlisted for 1st round.

Round 1 (Coding Test): Online test was conducted on the Codility platform. There were 3 questions which are to be solved in 1.5 hours.

  • 1st Question is a basic array and sorting implementation.
  • 2nd Question in Medium 2d-DP question. ( Not a standard Question)
  • 3rd Question is a DP question again wherein you have to find a proper substring of a given substring which is both a suffix and prefix.
    I have solved 1st question and 2nd questions completely and the 3rd one with 70 to 80 percent.

Note: You need to submit your code on basis of example test cases only once submitted cannot be changed, So take good care of all edge cases.

18 were qualified for 2nd round.

2nd Round(1st tech interview-1hr): It started with an intro from both sides, then we have to choose a programming language we are comfortable with. I choose C++, and he asked me questions related to C++ and went deep to understand my depth in the same. Then questions on DBMS(acid properties, different types of key, query of 3rd highest salary), OS(scheduling algorithms, process, threads), Computer networks(OSI layer, difference between TCP and UDP, VPN, Etc.), and OOPS. Then he gave 1 pseudocode and asked for the output. Finally, he asked for 2 DSA problems both were easy but they checked for an optimized solution, and time complexity is important.

Finally, only 10 moved to 3rd round and I was one among them.

DSA Problems are-

  • Longest Common Substring of String Sequence
  • Print the left view of Binary Tree

3rd Round(2nd tech interview-1hr): First was intro then he asked a DSA problem to solve, I gave a brute force approach but couldnā€™t give an optimized solution the interviewer was not helpful and he skipped it after a few minutes and he asked some technical questions on OS, DBMS, Networks, etc. Unfortunately, I was not qualified in this round, and the other person qualified for the next round.

4 students are qualified for this round.

4th Round(Hr interview 30min): The other person who qualified for this round was told that it was a non-elimination round and standard HR questions were asked like

  • Tell me about yourself
  • What are your strengths and weaknesses
  • Do you have any offers?
  • Why Hashedin?
