Rubrik Software Engineer interview rounds

  1. Online Assessment: Four coding problems in roughly 75 to 90 minutes, reported at Codeforces 1700+ level. Topics reported include combinatorics, tree DP, array operations and binary search. Solving two fully was enough to move forward for at least one candidate.
  2. Phone Screen
  3. Concurrency / System Coding Round
  4. Code Design Rounds
  5. System Design Rounds
  6. Director / Behavioral Round
  7. Technical Deep Dive on Past Projects

Questions reported in Rubrik Software Engineer interviews

  1. Write code for a task scheduler (the interviewer was effectively asking for an implementation of thread.start and thread.join).
  2. Explain the basics of concurrency, mutexes, locks, semaphores and task scheduling in an operating system.
  3. Implement a stack using a linked list and make it thread-safe, with executable code.
  4. Implement the thread-safe stack using a CAS (compare-and-swap) approach.
  5. Phone screen: a variant of LeetCode Stamping the Grid, where the optimal solution uses prefix sums to reach O(MN).
