Practise Amazon interview questions.
Free practice for Amazon SDE, PM, and EM interviews. Leadership-principle behavioural prep, system-design back-of-envelope estimation, the MCQ library, and written preparation guides to the loop.
What the Amazon loop actually looks like.
Amazon's loop has its own grammar: every round (technical or otherwise) is graded against the 16 Leadership Principles. Bar Raisers ask LP questions in the middle of a coding round. SDE loops include coding + system design; SDM loops swap coding for behavior + management depth.
Coding rounds
Algorithms, data structures, occasionally OO design. LP questions woven in throughout. A "tell me about a time you..." mid-coding is normal.
System design (SDE II+)
Practical and component-focused: caching layers, queues, idempotency, retries. Capacity estimation expected.
Bar Raiser
An interviewer from outside the team whose job is to keep the bar high. Heavily LP-anchored.
Leadership Principles (every round)
Customer Obsession, Ownership, Bias for Action, Dive Deep. Bring two or three specific stories per principle.
Topics Amazon interviewers lean on.
Practise the languages Amazon screens on
What separates offers from rejections at Amazon.
- 1
Memorise the 16 LPs. Map two stories per principle. Without these you cannot pass.
- 2
For Bar Raiser, bring your sharpest, highest-impact story.
- 3
On system design, walk through capacity early. It's a signal for Dive Deep.
- 4
STAR-format your behaviorals: Situation, Task, Action, Result. Finish the Result with a number.
Train the muscle, not the answer.
Thousands of free MCQs, AI-graded guesstimate practice, and an AI tutor. Every practice question and its grading rubric is free to read before you start. AI grading is capped at 1 answer a day on the free plan and 30 a day on Pro.
Round-format and topic claims are sourced from the public interview-prep press above. We refresh these as companies update their loops.
