5 rounds total. 2 screening rounds. 3 onsite rounds.

• Multithreading round: Design an atomic stack using a linked list node.
• Coding round: Given a range (x, y), create a random number generator using an array and a custom shuffle function.

Onsite:

• Coding round: Implement a Binary Search Tree (BST) along with inorder traversal.
• Multithreading round: Discuss memory management and systems concepts, and solve an easy LeetCode problem on overlapping intervals.
• Behavioral round: Mostly resume and background-based questions, no specific topics mentioned. This round was relatively easy.

Result: Rejected, possibly due to weak technical performance in the final rounds. However, the HR and team were pleasant to interact with. The hiring bar appears to be relatively high.

List all the questions above.

For multithreading round practice:

• Job scheduling
• Bathroom problem
• Atomic queue/stack

For coding, look through LeetCode past months tagged with Rubrik.

There is one website, enginebogie, that has good, detailed interview experiences for Rubrik, so you can refer to that (not affiliated).

Good luck!
