Amazon OA Questions: What SDE Intern & Graduate Roles Ask
Amazon Online Assessment patterns for India SDE Intern / new grad — OA coding themes, Leadership Principles MCQs, timing tips, and how to prepare without grinding random hard problems.
Amazon OA is less about obscure puzzles and more about clean medium DSA under time, plus Leadership Principles signals in work-style questions.
Typical Amazon OA structure
India SDE Intern / graduate OAs usually combine coding (often two problems, ~70–90 minutes depending on loop) and a work-style / LP-aligned questionnaire. Some loops add debugging or system-design light sections for experienced hires — freshers should prioritise arrays, graphs/BFS-DFS, hashing, and heaps.
- Coding: 1 medium + 1 medium-hard is common; sometimes two mediums
- Work style: choose options that map to Ownership, Bias for Action, Dive Deep, Earn Trust
- Partial credit: always ship a correct brute force before optimising
Question themes that recur
You will see variations — not the same LeetCode IDs every time — but themes stay stable: sliding window on strings, top-K with heaps, BFS shortest path on grids, prefix sums, monotonic stack, and hashmap pair counting. Practise writing tests for edge cases (empty input, n=1, duplicates).
Leadership Principles in the OA
Don’t pick ‘hero’ answers that ignore the team or data. Amazon wants bias for action with customer impact, not cowboy coding. If two options look good, pick the one that owns the outcome and escalates with data.
Day-of strategy
Read both problems first. Start with the one you can finish. Leave 10 minutes to dry-run. Name variables clearly — human review happens later in phone screens. Never leave a blank submission if you have a partial solution.
After OA — what Apply helps with
Use Interview prep with Amazon + your tailored resume to drill LP stories (STAR) and coding follow-ups. Align your Projects section to scale, customer impact, and metrics before the phone screen.
