The Holdouts
In our push-notification log, each message records the plan tier it targeted in the `platform` field. Find the unique users who were sent a `basic`-tier notification but never a `premium`-tier one.
The Overlap
Your monitoring system logs server maintenance as `[start, end]` minute ranges, and windows that overlap or sit back-to-back really describe one continuous outage. Collapse the `windows` so any that overlap or touch at an endpoint become a single range, and return them ordered by start time. Two windows touch when one ends exactly where the next begins.
Split Decision
We run dozens of product experiments at once on our consumer app, and each user who enters an experiment is locked to a single variant for its duration: either the control or one of the treatment groups. Analysts measure lift by comparing what users in each variant did after they were enrolled, joining their assignments back to our existing event log. Design the data model so a user can never land in two variants of the same experiment and so only post-enrollment behavior counts toward a variant's metrics.
The Upper Rungs
A compensation team is setting reference points for a new salary-band ladder, where a value that appears more than once still counts only once. Return the five highest values from the employee metrics table, highest first.

The reference market for US tech comp. Highest base DE salaries in the US, highest cost of living, deepest senior-engineer hiring pool.
Amazon's San Francisco Bay Area office hires at the company's reference compensation band. The San Francisco Bay Area office's interview loop mirrors the global loop structure; team assignment and comp-band negotiation are the main local variables.

The loop
How the interview actually runs
01Recruiter screen
30 minLogistics, team fit, and a light Leadership Principle question. Recruiters confirm seniority expectations before booking the loop. Misalignment here can downlevel the loop.
- →Have a 60-second pitch that names 2-3 concrete data systems you've built
- →Confirm the team. Amazon has hundreds of DE teams across AWS, Retail, Ads, Alexa, Prime Video, Pharmacy
- →Ask about the comp band early to avoid end-of-loop misalignment
02Technical phone screen
60 min1 SQL problem, 1 Python or pipeline design problem, and 10-15 min of Leadership Principle questions. The SQL is harder than the Online Assessment, expect multi-step window functions or self-joins.
- →Narrate approach before writing code. Amazon grades process, not just the final answer
- →Name the LP before telling the story
- →Prepare at least 2 stories per LP; follow-ups probe a third story on the same theme
03Onsite: SQL deep-dive
60 min2 to 3 SQL problems with escalating difficulty, usually in Amazon contexts (seller performance, order fulfillment, inventory). Ends with 10 min of LP questions.
- →Practice window functions across large partition cardinalities
- →Be ready to rewrite correlated subqueries as joins and vice versa
- →When asked about optimization, mention partition pruning and columnar storage
04System design (pipeline architecture)
60 minDesign a production pipeline end-to-end: ingestion, transformation, storage, consumers, SLAs, failure modes, backfill strategy, and cost trade-offs. At senior level, you drive the conversation without prompting. Expect follow-ups about scale, cross-team coordination, and operational load.
- →Anchor on the SLA and data shape before diagramming
- →Discuss idempotency, partitioning, and backfill explicitly
- →Estimate cost: 'This pipeline will cost roughly $X/month at this volume'
05Onsite: Bar Raiser
60 minAn interviewer from outside the hiring team with veto power. Heaviest on Leadership Principles, with one harder technical problem. Checks whether you raise Amazon's hiring bar.
- →Bring a story where you were wrong and had to change course
- →Quantify impact: cost saved, latency reduced, users affected
- →If you don't know something, say so. Fabricating kills the loop faster than any technical gap
Level bar
What Amazon expects at L6 Senior Data Engineer
Independent technical leadership
Senior DEs drive pipeline designs without engineering manager involvement. Interviewers probe whether you can decompose ambiguous requirements, make architecture trade-offs, and defend your choices under scrutiny.
Cross-team coordination
Senior scope regularly spans multiple teams. Expect scenarios about a downstream team missing an SLA because of a change you made, or negotiating a schema migration with the team that owns the upstream source.
Production operational rigor
Fluent in on-call, alerting, data quality checks, and incident response. Dive-deep stories at this level should include correlating a metric drop to a specific commit or a timezone bug or a subtle ordering issue, not 'I looked at the logs.'
Amazon-specific emphasis
Amazon's loop is characterized by: Leadership Principles woven into every round, with a Bar Raiser holding veto power. Calibrate your preparation to that, generic FAANG prep will not close the gap on company-specific expectations.
Behavioral
How Amazon frames behavioral rounds
Dive Deep
The most relevant LP for data engineers. Amazon wants DEs who trace anomalies through 3+ layers of the stack instead of patching symptoms.
Ownership
You built it, you own it, including on-call and long-term maintenance. Ownership extends beyond your explicit scope when dependencies break.
Bias for Action
Speed beats perfection. Amazon wants DEs who ship V1 in 2 weeks rather than a perfect solution in 3 months.
Earn Trust
Trust comes from delivery and transparency. Bar Raisers check whether you can admit mistakes and communicate setbacks without spinning.
Prep timeline
Week-by-week preparation plan
Foundations and gap analysis
- ·Do 10 medium SQL problems. Note which patterns feel slow
- ·Write out 2-3 behavioral stories per value, Amazon weights this round heavily
- ·Read Amazon's public engineering blog for recent architecture patterns
- ·Review your prior production work, pick 3-5 projects you can discuss in depth
SQL and coding fluency
- ·Practice window functions until DENSE_RANK, ROW_NUMBER, LAG, LEAD are reflex
- ·Do 20+ Amazon-style problems in their domain
- ·Time yourself: 25 min per medium, 35 min per hard
- ·Record yourself narrating your approach aloud. Interviewers weigh how you explain it, not only what you write
Pipeline system design
- ·Design 5 pipelines on paper: daily aggregation, clickstream, CDC, ML feature store, real-time alerting
- ·For each, write SLA, partition strategy, backfill plan, and cost estimate
- ·Practice with a friend, senior-level system design is 50% driving the conversation
- ·Review Amazon's open-source and engineering blog for in-house patterns
Behavioral polish and mock loops
- ·Rehearse every story out loud. Cut to 2-3 minutes each
- ·Run 2 full mock loops with a senior DE or coach
- ·Identify your 3 weakest behavioral areas and draft additional stories
- ·Review recent Amazon news or earnings call for fresh talking points
Taper and logistics
- ·No new content. Review your notes only
- ·Sleep. Mental energy matters more than one more practice problem
- ·Confirm logistics: laptop charged, shared-doc tool tested, snack and water nearby
- ·Remember: the loop is rooting for you to raise the bar, not to fail
