Hello Everyone!!

I wanted to share my interview experience with Rubrik for the 2025 Grad role. A recruiter reached out to me directly for this position.

Timeline: The overall process took place during the 2nd and 3rd week of September.

Online Assessment (OA)

Duration: 1 hour

Questions:

1 DSA question (based on DP on strings — can’t share the exact problem).

10 MCQs on Multithreading and Concurrency.

I cleared the OA and got a call for interviews. The recruiter scheduled 2 interviews on consecutive days.

Round 1

Format: Two interviewers were present.

Question: (Similar to) Design and implement a Linux file system.

It was an open-ended problem, so I had to ask a lot of clarifying questions.

I managed to fully implement 3 parts and partially complete the 4th part.

Last 10 minutes: Open Q&A with the interviewers.

Round 2 (Next Day)

Format: Debugging round.

Task: The interviewer gave me a multithreading/concurrency-based code and asked me to:

Find and fix all bugs.

Provide a proper running code within 50 minutes.

I was able to identify the main bug (deadlock) and fixed it. Unfortunately, after the fix, the code failed to compile. I spent a lot of time trying to resolve this issue and couldn’t address the other bugs.
At the end, the interviewer clearly mentioned that they expected a fully working code solution.

Result

I was rejected after 2 rounds, but overall it was a great learning experience. I really enjoyed the process and hope this write-up helps those preparing for similar interviews.

PS: Feel free to drop your questions in the comments, and I’ll be happy to answer them.

All the best! ✨
