Interview Process

Stage-by-stage, with tips and sample questions

1

Online Assessment

Timed coding test on a platform (HackerRank/Codility) with 2–3 DSA problems and sometimes MCQs on CS fundamentals.

Tips
  • Solve 150–250 LeetCode problems (easy→medium→hard)
  • Master arrays, strings, trees, graphs, DP
  • Dry-run edge cases before submitting
Sample questions
  • Two-pointer / sliding-window array problem
  • Tree traversal / lowest common ancestor
  • Dynamic programming (knapsack/LIS variant)
  • MCQs on time complexity & OS
2

Technical Round (DSA)

Live coding with an engineer. You explain your approach, optimise complexity, and write working code.

Tips
  • Think out loud — communication is scored
  • State brute force, then optimise
  • Discuss time & space complexity explicitly
Sample questions
  • Design an LRU cache
  • Detect a cycle in a linked list
  • Number of islands (BFS/DFS)
  • Find median of two sorted arrays
3

System / Design Round

For some roles: high-level design or low-level design (machine-coding) to test scalability and OOP modelling.

Tips
  • Learn fundamentals: load balancing, caching, sharding, queues
  • Clarify requirements before designing
  • Discuss trade-offs, not just one answer
Sample questions
  • Design a URL shortener
  • Design a rate limiter
  • Low-level design of a parking lot
  • How would you scale a notification system?
4

Behavioral / Bar-Raiser Round

Values and leadership-principles based. Uses your past experiences to predict how you work.

Tips
  • Prepare 6–8 STAR stories (Situation-Task-Action-Result)
  • Map stories to the company’s leadership principles
  • Show ownership, data-driven decisions, and impact
Sample questions
  • Tell me about a time you disagreed with a teammate.
  • Describe your most challenging project.
  • A time you took ownership beyond your role.
  • How do you prioritise when everything is urgent?
