Amazon Online Assessment (OA) AI Helper — Coding & Work Styles
Amazon's Online Assessment (OA) is delivered on HackerRank or Codility and mixes two timed coding problems with a work simulation and a work-styles survey tied to the Leadership Principles. The coding section is where AI help applies.
What the Amazon OA contains
- Coding (Part 1) — two algorithmic problems, typically 70–90 minutes.
- Work Simulation — scenario-based judgement tied to the Leadership Principles.
- Work Styles Survey — personality/values questionnaire.
The coding platform (HackerRank/Codility) logs tab switches and paste events; some OAs add webcam proctoring.
The coding section is the decisive one
Amazon weights the two coding problems heavily and later interviews may revisit your OA solutions — so understand what you submit. Use AI to solve and to explain the approach, then auto-type the code at a natural pace. Because Codility replays your keystroke timeline, pasting is a clear flag; typing is not. See our assessment guide.
Handling the behavioural parts
The work simulation and work-styles survey are about consistency with the Leadership Principles, not correctness. AI can help you prepare a consistent framing beforehand, but answer them yourself — they're not proctored-code sections.
Solve the Amazon OA coding round on one screen
UFOlee overlays ChatGPT/Claude/Gemini on your Amazon OA — no tab switch, one-hotkey screenshot, hardware auto-typing that reads as natural in the keystroke replay. Free tier, one-time $12.

Does the Amazon OA detect UFOlee?
The coding platform (HackerRank/Codility) flags focus loss and paste. UFOlee overlays the AI so you never switch tabs and types with hardware keystrokes, producing a natural keystroke timeline.
Will Amazon interviewers ask about my OA solution?
They can. Use AI to understand the approach, not just copy it, so you can walk through your OA code in the interview loop.
Is UFOlee free for Amazon OA prep?
Yes, there's a free tier; one-time passes start at $7.
