There were 5 rounds in the selection process.
OA:
- Aptitude section
- MCQ section(coding and CS fundamentals(especially OOPs and JAVA))
- 2 coding questions
15 students were shortlisted for further rounds.
Interview Round 1(40 mins | DSA):
- https://leetcode.com/problems/number-of-islands/
- https://leetcode.com/problems/number-of-distinct-islands/ (given the grid as in first question, find the count of distinct shapes in the grid)
I had given the optimal solution for both the problems and was able to write the complete code for the two. 7 students were shortlisted further(including me).
Interview Round 2(40 mins | DSA | Subjects):
- https://leetcode.com/problems/word-ladder/
- We then discussed set and hashTable, their working (self-balancing BST, hash functions, etc).

- He asked me about MRU(most recently used page algorithm: OS) and about its real-life application.
- Difference between abstract class and interface and examples for it and why do we use it.
He then asked whether I had written the complete codes for previous rounds and then gave me two basic coding questions. I was asked only for the logic and not the code (for both)
- https://leetcode.com/problems/group-anagrams/
- https://www.geeksforgeeks.org/check-if-two-given-strings-are-at-edit-distance-one/amp/
I was able to answer all questions and give an optimal solutions for the coding problems. I advanced to next round.
