Practice problems
Airbnb senior data engineer practice set
Practice sets surfaced for Airbnb senior data engineer candidates by the same model that reads their job postings. Each card opens a working coding environment.
Subscribers Without Premium
Pull basic-plan subscribers who never upgraded to premium from the subscriptions data. The retention team wants to run a winback campaign targeting this group.
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.
Letters in the Noise
A text-cleaning step in your pipeline needs a per-letter tally of the raw strings flowing through it. For a given `s`, return how many times each letter appears, treating uppercase and lowercase as the same letter and ignoring any character that is not a letter. Give the results as `[letter, count]` pairs in lowercase, ordered alphabetically.
Daily signup-to-purchase funnel
Count signups and first-time purchases per day. Product-company favorite.

The loop
How the interview actually runs
01Recruiter screen
30 minStandard call. Airbnb recruiters probe cultural alignment early, the Core Values round later in the loop can veto strong candidates.
- →Know Airbnb's 4 core values: Champion the Mission, Be a Host, Embrace the Adventure, Be a Cereal Entrepreneur
- →Product sense stories are welcome early, even in a DE track
- →Be specific about the team: Trust, Search, Marketplace, Experiences
02Technical phone screen
60 minSQL + Python. Airbnb SQL is heavy on marketplace / two-sided data: host-guest matching, booking funnels, cancellation patterns.
- →Prepare for marketplace SQL: hosts, listings, bookings, reviews
- →Python problems are practical: data cleaning, anomaly detection
- →Expect ambiguous problem statements, asking clarifying questions is a must
03Onsite: SQL + product analytics
60 minSQL deep-dive with a product-sense layer. 'Define a metric for X. Now write SQL to compute it.' Airbnb cares whether you can translate business questions into data.
- →Practice metric definition: define DAU, define bookings-per-search, define cancellation rate
- →Strong answers include what the metric does NOT capture
- →Be explicit about data-quality assumptions
04Onsite: data system design
60 minDesign a data pipeline for a marketplace-relevant system: search ranking, trust & safety signals, host payouts.
- →Think about both sides of the marketplace, hosts and guests have different data needs
- →Trust & Safety come up often, design for detection of bad actors
- →Cover backfill and historical corrections explicitly
05System 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'
06Core values interview
45 minAirbnb's core-values round is famously decisive. Interviewers assess cultural alignment against the four values. Technically strong candidates can fail the loop here.
- →Have 2+ stories per core value
- →Champion the Mission is about belonging / travel, frame data work in terms of user trust and experience
- →Be a Host is about empathy, stories about stepping into others' shoes
Level bar
What Airbnb expects at 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.'
Airbnb-specific emphasis
Airbnb's loop is characterized by: Product-sense-heavy with a core-values round that is genuinely decisive. Calibrate your preparation to that, generic FAANG prep will not close the gap on company-specific expectations.
Behavioral
How Airbnb frames behavioral rounds
Champion the Mission
Airbnb's brand mission is belonging. Even DEs are expected to frame their work in terms of user experience and trust.
Be a Host
Empathy and service orientation. Stories about helping colleagues or users through difficulty.
Embrace the Adventure
Comfort with ambiguity and taking on unfamiliar problems. Airbnb wants people who learn fast.
Be a Cereal Entrepreneur
Resourcefulness and scrappy problem-solving. Stories about solving problems without the right tools or sufficient support.

- ·Time yourself: 25 min per medium, 35 min per hard
- ·Record yourself narrating approach aloud, communication is graded
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 Airbnb's open-source and engineering blog for in-house patterns
