The Amazon Work Simulation assessment puts you inside a fictional Amazon team for around an hour and asks you to do the job rather than describe it. You read internal messages, interpret data, choose between competing priorities and write short responses. Amazon’s own guidance for university software roles lists the Work Simulation at an average of 60 minutes, alongside a Coding Assessment at an average of 70 minutes, a Workstyles Assessment at an average of 15 minutes and a 5 minute feedback survey, and tells full-time candidates to set aside up to two hours of uninterrupted time for the online assessment. The simulation is not a knowledge test. It scores judgement, and the judgement it scores is defined by Amazon’s 16 Leadership Principles.
TL;DR
- Amazon’s Work Simulation averages 60 minutes and sits inside a longer online assessment that can take up to two hours in total.
- For university software roles, the full-time online assessment includes the Coding Assessment, Workstyles Assessment, Work Simulation and a feedback survey. Internship assessments are around 90 minutes and do not include the Work Simulation.
- Tasks mirror real work: reading a data chart, answering a customer message, prioritising an inbox, and picking between imperfect options.
- Scoring is anchored on Amazon’s 16 Leadership Principles, including Customer Obsession, Ownership, Bias for Action, Dive Deep and Earn Trust.
- The Workstyles Assessment is a separate personality-style section. Answer it honestly and consistently rather than trying to guess a target profile.
- Prepare by learning the Leadership Principles well enough to apply them to a decision, not to recite them.
What is the Amazon Work Simulation assessment?
The Work Simulation is a scenario-based module in Amazon’s online assessment. You are placed in a role and given realistic artefacts: emails, chat messages, dashboards, customer complaints, a schedule that does not fit. You then choose or write responses. It is closer to an in-tray or e-tray exercise than to a maths test.
Amazon publishes the module list and average timings for university software roles. Full-time candidates see a Coding Assessment (average 70 minutes), a Workstyles Assessment (average 15 minutes), a Work Simulation (average 60 minutes) and a Feedback Survey (average 5 minutes), and Amazon advises setting aside up to two hours of uninterrupted time. Internship assessments are described as taking about 90 minutes and list the Coding Assessment, Workstyles Assessment and Feedback Survey without the Work Simulation. Other Amazon job families use their own versions of the simulation, so check the invitation you were sent.
If your process also includes a data-heavy section, drill the arithmetic separately. Ten minutes on five free timed numerical questions is enough to get the mental maths moving before you start.
What does the assessment measure?
Amazon’s interview process is built around its 16 Leadership Principles, and candidates are pointed at them as core preparation material. The simulation applies the same lens earlier in the funnel. The principles most visible in simulation tasks are these.
| Leadership Principle | What it looks like in a simulation task |
|---|---|
| Customer Obsession | Starting from the customer’s problem rather than internal convenience |
| Ownership | Fixing the issue in front of you instead of routing it away |
| Dive Deep | Checking the underlying number before acting on a summary |
| Bias for Action | Deciding quickly when the decision is reversible |
| Earn Trust | Telling people the bad news early and plainly |
| Insist on the Highest Standards | Not shipping the quick fix that leaves the defect in place |
| Invent and Simplify | Removing a step rather than adding a process |
| Are Right, A Lot | Seeking one more data point before a hard call |
Two of these pull against each other on purpose. Bias for Action says speed matters and many decisions are reversible. Dive Deep says stay connected to the detail. A good simulation answer shows you know which one the situation calls for: move fast on a reversible decision, verify first on an irreversible one.
Sample question 1: prioritising a busy inbox
It is 09:00. You are covering a delivery station queue. Four items are waiting and you have time to start one.
- A: A customer says a fragile parcel arrived broken. They have a replacement due tomorrow already booked.
- B: A dashboard shows one route’s on-time rate dropped from 96 percent to 71 percent overnight. No one has flagged it.
- C: A colleague asks you to review their slide deck for a meeting next week.
- D: A supplier email asks for confirmation of an order quantity by end of day.
Which do you start first, and what is the correct order?
Worked solution. Sort by two questions: is a customer being harmed right now, and is the problem still growing?
B is first. A route running at 71 percent on-time is harming customers continuously, nobody has noticed, and every hour makes it worse. Starting here is Customer Obsession plus Ownership, because the task is unowned. D is second: it has a hard deadline today and takes minutes, so clearing it prevents a second problem tomorrow. A is third: the customer is unhappy, but a replacement is already booked, so the immediate harm is contained and a short acknowledgement is enough for now. C is last: it is genuinely useful, but it is a week away and no one is affected by a delay.
The order is B, D, A, C. The common wrong answer is A first, because it is the most emotionally urgent item. The simulation rewards the candidate who spots that the unflagged systemic problem is the bigger customer issue.
Sample question 2: reading the data before you act
A weekly report shows returns for one product category.
| Week | Units shipped | Units returned |
|---|---|---|
| Week 1 | 20,000 | 400 |
| Week 2 | 12,000 | 336 |
A colleague writes: “Good news, returns fell 16 percent this week.” Do you agree, and what should you say?
Worked solution. The raw count did fall: 400 to 336 is a drop of 64, and 64 divided by 400 is 16 percent. But shipments also fell, so the rate is the number that matters.
- Week 1 return rate: 400 divided by 20,000 = 2.0 percent.
- Week 2 return rate: 336 divided by 12,000 = 2.8 percent.
The return rate rose from 2.0 percent to 2.8 percent, an increase of 0.8 percentage points, which is a 40 percent relative increase. Returns got worse, not better. The right response is to reply with the rate calculation, say plainly that the headline is misleading, and ask what changed in week 2.
This is Dive Deep and Earn Trust in one answer. It is also a standard percentage trap, and the same pattern appears in ordinary aptitude tests, which is why the drills in our numerical reasoning test tips transfer directly to simulation tasks.
How should you answer the written and video parts?
Some simulation tasks ask you to write a short message rather than pick an option. Three rules cover most of them.
Lead with the decision or the answer, not the background. Give the reason in one sentence, with a number if you have one. Then state what you will do next and by when. Amazon’s interview guidance points candidates at behavioural questions and the STAR method, and the same discipline of situation, task, action and result keeps a written simulation answer short and specific.
Do not write a paragraph apologising or hedging. A message that says what happened, what you are doing about it, and when the recipient will hear next is a stronger answer than one that lists every consideration you weighed.
How do you prepare for the Amazon Work Simulation?
- Read the 16 Leadership Principles once, then practise applying two or three of them to a decision. Recitation does not help; application does.
- Practise ranking tasks against each other. The skill is deciding what not to do, and it is the same skill tested in our situational judgement test guide.
- Practise reading a table and converting counts into rates. Most data traps in simulations are rate versus count, or percentage points versus percent.
- Book the full window. For a full-time software role Amazon advises up to two hours of uninterrupted time, so do not start it 45 minutes before a lecture.
- Treat the Workstyles Assessment as honest self-report. It is short at around 15 minutes, and consistency across items matters more than picking heroic answers.
- Sort your setup first: stable connection, charged laptop, quiet room. The checklist in how to pass online assessment tests applies here.
If you are also applying to graduate schemes elsewhere, the scenario formats overlap heavily with the ones described in our Big 4 online assessment guide and with the game-based screens in our pymetrics games guide.
Frequently Asked Questions
How long is the Amazon Work Simulation?
Amazon lists an average of 60 minutes for the Work Simulation in its university software online assessment, and advises full-time candidates to set aside up to two hours for the whole assessment.
Is the Work Simulation the same as the Workstyles Assessment?
No. They are separate modules. The Workstyles Assessment averages 15 minutes and is a self-report questionnaire. The Work Simulation is a longer scenario exercise where you perform tasks.
Do interns take the Work Simulation?
Amazon’s published university guidance lists the internship online assessment as about 90 minutes with the Coding Assessment, Workstyles Assessment and Feedback Survey, and does not include the Work Simulation for that path.
Can you pause the Amazon online assessment?
Plan on completing it in one uninterrupted sitting. Amazon’s advice to set aside up to two hours exists precisely because stopping partway is not something you should rely on.
Should you answer the Workstyles questions strategically?
No. Answer honestly. The questionnaire is short and repeated themes make inconsistent answers visible, so an engineered profile is more likely to weaken your application than strengthen it.
How important are the Leadership Principles?
They are central. Amazon points candidates at the Leadership Principles as core preparation, and the simulation scenarios are written so that the better answer is the one that reflects them, especially Customer Obsession, Ownership and Dive Deep.
