Hey community, I recently gave interview for Senior MTS position with OCI India. Got negative feedback, but still here are the questions that were asked.

Eliminator Round:-
Check if words are anagrams. EASY.
LRU Cache. MEDIUM
Couple of behavioural questions. Some questions on concurrency.

Got call 2 days later that they will take my loop interview. My interviews were scheduled for 2 days. Daily 2 interview

Loop Interview 1:
Group Anagrams from a list of strings. MEDIUM
Maximum Subarray
Print odd even using two threads concurrency problem.
Some behavioural questions

Loop Interview 2:
This was taken by someone from US.
Rain water trapping problem. HARD
Generate valid parenthesis (backtracking problem). MEDIUM
Some behavioural questions. This was where I froze completely and could not communicate properly at all.

Loop Interview 3:
This was with Hiring manager from India. He asked lots of technical questions from my resume. He also gave lots of system design situational based questions. I was asked to design CONFLUENCE.

Loop Interview 4:
This was my bar tender/bar raiser round. Plenty of behavioural questions were asked.

Result: REJECTED.

I hope it helps the community in their prep. I applied through their web page. Good luck guys.

Thank you
