Amazon Interview Guide 2026

Amazon's Interview Loop Structure

Amazon's standard SDE loop is 5-7 rounds conducted virtually. For SDE-I (entry-level): 1 technical phone screen plus 4-5 virtual onsite rounds mixing coding and behavioral. For SDE-II and above: add a system design round. Total timeline is typically 3-6 weeks from recruiter contact to offer.

What makes Amazon structurally unique: every loop includes a Bar Raiser, an interviewer trained specifically to calibrate your seniority level relative to current Amazon engineers. The Bar Raiser can veto a hire that the hiring team wants to make. They are not on the hiring team and have no stake in filling the position.

Leadership Principles: The Core of Every Amazon Interview

Amazon's 16 Leadership Principles are not a cultural statement, they are the scoring rubric. Every behavioral question at Amazon maps to one or more LPs. Interviewers document your response against specific LPs in their feedback, and the debrief discussion is structured around LP coverage. A technically perfect candidate with weak LP answers will not pass.

The most tested LPs based on LeakCode candidate reports: Customer Obsession, Ownership, Bias for Action, Deliver Results, Dive Deep, and Earn Trust. Prepare at least two distinct STAR stories for each of these six. The stories should cover different time periods and situations to avoid repetition across interviewers.

The single most common Amazon behavioral mistake: stories where "we" is the subject. Amazon interviewers will interrupt and ask "what did you specifically do?" Reframe every story around your individual actions, decisions, and outcomes. The word "I" should appear far more than "we."

Coding Rounds at Amazon

Amazon coding rounds use a proprietary IDE (CodeSignal or their internal tool). The bar is medium-difficulty LeetCode with a strong emphasis on working code over partial solutions. Unlike Google, Amazon interviewers often expect you to get to a running solution, not just a correct approach.

Most frequently reported topics in LeakCode's Amazon coding data: arrays and strings (most common), trees and graphs, dynamic programming, and system-level design problems (rate limiters, caches). Amazon is also known for OOP design questions at mid-level, such as designing a parking lot or a library system.

Each coding round also includes behavioral questions. You will be asked 1-2 LP-based questions before or after the coding problem in the same session. Do not treat coding rounds as purely technical, prepare LP stories for every round.

System Design at Amazon

System design is required for SDE-II and above. Amazon's rubric emphasizes: operational awareness (monitoring, alerting, on-call), cost consciousness (you are designing on AWS, cost matters), and customer impact framing. Start every design by framing the customer experience before touching infrastructure.

Common Amazon system design questions: design Amazon's shopping cart, design a notification service, design a URL shortener, design DynamoDB's storage layer, design a distributed locking service. The recurring theme is AWS-native components. Know S3, DynamoDB, SQS, SNS, Kinesis, and Lambda at a conceptual level before your interview.

The Bar Raiser Round

The Bar Raiser round is indistinguishable from any other interview. You will not know which interviewer is the Bar Raiser. They may conduct a coding round, system design, or pure behavioral. Their job is to ensure you are above the median Amazon engineer at your target level.

Bar Raiser rounds tend to go deeper. Expect follow-up questions on every answer: "Why did you choose that approach?", "What would you do differently now?", "Walk me through the tradeoffs." The Bar Raiser is probing for depth, intellectual honesty, and evidence that you raise the bar rather than meet it.

Leveling at Amazon

Amazon levels run SDE-I (L4), SDE-II (L5), SDE-III (L6), Principal (L7), Senior Principal (L8). Most experienced hires enter at SDE-II. Level calibration happens during debrief, not during the interview itself. If your signal is between levels, Amazon tends to downlevel rather than reject.

Compensation at Amazon is heavily equity-weighted. The RSU vesting schedule (5% year 1, 15% year 2, 40% year 3, 40% year 4) is unusual. Base salary is capped lower than Google or Meta. Negotiate the signing bonus aggressively if Amazon offers you, as it compensates for the back-weighted vest.
