Amazon SDE Online Assessment (SDE-1 / New Grad / Intern - university & campus hiring)

Difficulty: moderate4 sections

Compiled from public sources, verify before you rely on it. Amazon revises this test regularly. Source corroboration: Well-corroborated. Re-checked 2 Nov 2026 (OPR-RES-010) against Amazon's own university SDE assessment page (parts and average minutes) and 2025-26 candidate reports. Amazon adjusts the OA most cycles: confirm the parts and timings in your own invite email.

Test structure

Reported

Coding assessment

2 problems (reported; Amazon does not state the count) questions
~70 on average (official) minutes
  • Arrays & strings
  • Sliding window and hash maps (the most reported pattern)
  • Greedy and binary search on the answer
  • Trees, BFS/DFS and graphs
  • Dynamic programming
  • Heaps / priority queue
  • You may skip a problem and come back to it (official)
  • Public documentation such as JDK or STL docs is allowed; login-gated sites are not (official)

Work Simulation (full-time roles only)

scenario-based (count not published) questions
~60 on average (official) minutes
  • A simulated SDE workday: emails, status requests, a blocked teammate, prioritising and debugging judgement (reported)
  • Choose or rate responses; scored against Amazon's Leadership Principles (reported)
  • Internship OAs skip this part (reported)

Workstyles Assessment

statements (count not published) questions
~15 on average (official) minutes
  • Agree/disagree and most-like-me statements about how you work
  • Mapped to the Leadership Principles; one candidate blamed neutral answers for a rejection (single report)

Feedback survey

short survey questions
~5 (official) minutes
  • Candidate-experience survey; skipping it delays your results (official)

How the test works

Reported

Amazon's own university SDE assessment page gives the parts and their AVERAGE times: a coding assessment (about 70 minutes), a Work Simulation (about 60 minutes, full-time roles only), a Workstyles assessment (about 15 minutes) and a short feedback survey (about 5 minutes). The same page says to set aside up to two hours and that, depending on your country, the assessment comes in one or two parts; candidates report 3 to 4 hours end to end, so plan for the long case. Officially, browser activity is logged, a print-screen ends the session, and the test needs a laptop or desktop. Reported, not official: 2 coding problems in about 70 minutes for 2025 SDE-1 India candidates, on HackerRank, in the LeetCode easy-medium to medium band; internship OAs report 2 problems in 90 minutes with no Work Simulation. Some older reports describe typing your approach and time and space complexity in text boxes; 2026 reports do not confirm it. NEW IN 2026 (three independent reports, not yet on Amazon's page): some candidates get an AI-assisted variant of about 100 minutes, with one DSA problem plus one repository task where you fix bugs or finish a feature in an existing web codebase using an AI assistant built into HackerRank. Not every candidate gets it, and a plain DSA mock cannot simulate it. Languages, partial scoring and webcam rules are not published.

How the interviews go

Reported
  1. 1Technical 1: DSA x2 + 1 LP question
  2. 2Technical 2 / Bar Raiser: LP deep dives + 1 DSA
  3. 3Hiring manager (sometimes): projects, light scaling, LP

Working code for 1-2 medium DSA problems per round with complexity and edge cases; Leadership Principles in STAR form in every round; occasional LLD (custom data structure) or CS fundamentals for interns.

Based on several candidates' reports, checked 2 Nov 2026. Interviews vary by drive and interviewer.

What to prep

  • Sliding window and hash maps first (the most reported pattern), then arrays and strings, greedy, binary search on the answer
  • Trees, BFS/DFS, graphs, heaps and dynamic programming
  • Solve Amazon-tagged LeetCode mediums under a strict clock: 2 problems in about 70 minutes
  • Take Amazon's official practice assessment to learn the editor and the skip-and-return flow
  • Study the 16 Leadership Principles with STAR-style examples; they drive the Work Simulation and Workstyles answers
  • Answer Workstyles statements decisively and consistently rather than neutrally
  • If you may get the 2026 AI-assisted format, practise reading and fixing an unfamiliar codebase with an AI helper

Cut-offs and eligibility (indicative)

Reported

Not officially published - Amazon does not release section cut-offs. In practice the coding part is the hard gate: candidates report needing to pass all or most hidden test cases on both problems. The Work Simulation and Workstyles parts are scored on Leadership-Principle alignment, not a published pass mark. Any specific "X/2 problems" or percentage cutoff seen online is unofficial and cycle-dependent.
