Practice problems

Airbnb data engineer practice set

4 problems

Practice sets surfaced for Airbnb data engineer candidates by the same model that reads their job postings. Each card opens a working coding environment.

Pythonmedium~20 min

The Coin Vault

Given a target amount and a list of coin denominations, return the minimum coins needed using a greedy strategy: repeatedly take the largest coin that does not exceed the remaining amount. Return -1 if the greedy approach cannot make exact change.

Event Ticketing System Data Model

We run an IT helpdesk platform. Users submit support tickets, which are assigned to agents. Tickets go through multiple status changes before being resolved. SLA compliance is critical: P1 tickets must be resolved within 4 hours, P2 within 24 hours. Design the schema, and describe how you would load data from a JSON API feed into it.

The Queue That Wouldn't Stop Growing

Your streaming video event pipeline shows consumer lag spiking from near-zero to over 500,000 messages within two hours. You need to diagnose whether the cause is a producer burst or a consumer slowdown, then design a monitoring and auto-remediation system that can detect, alert on, and automatically recover from future lag events.

The Spread

Given a list of numbers, return the sample variance (sum of squared deviations divided by n-1), rounded to 2 decimals. Return 0.0 when fewer than 2 numbers.

The loop

How the interview actually runs

01Recruiter screen

30 min

Standard 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 min

SQL + 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 min

SQL 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 min

Design 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

05Core values interview

45 min

Airbnb'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 Data Engineer

Pipeline ownership

Mid-level DEs own pipelines end-to-end. Interviewers expect stories about designing, deploying, and maintaining a data pipeline that has been in production for 6+ months.

SQL + Python or Spark fluency

SQL is the floor. Most teams also expect fluency in either Python for data manipulation (pandas, airflow DAGs) or Spark for larger-scale processing.

On-call debugging

You should have concrete stories about production incidents: what alert fired, how you diagnosed, what you fixed, and what post-mortem action you owned.

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.

“How has your work connected to a real user experience?”

Be a Host

Empathy and service orientation. Stories about helping colleagues or users through difficulty.

“Tell me about a time you went out of your way to help a colleague or stakeholder.”

Embrace the Adventure

Comfort with ambiguity and taking on unfamiliar problems. Airbnb wants people who learn fast.

“Describe a time you took on something well outside your expertise.”

Be a Cereal Entrepreneur

Resourcefulness and scrappy problem-solving. Stories about solving problems without the right tools or sufficient support.

“Tell me about a time you solved a hard problem with limited resources.”

SQL and coding fluency

·Practice window functions until DENSE_RANK, ROW_NUMBER, LAG, LEAD are reflex
·Do 20+ Airbnb-style problems in their domain
·Time yourself: 25 min per medium, 35 min per hard
·Record yourself narrating approach aloud, communication is graded

4 weeks out

Pipeline awareness and behavioral depth

·Review pipeline architecture basics: idempotency, partitioning, backfill
·Practice explaining a pipeline you've worked on end-to-end in 5 minutes
·Refine behavioral stories based on mock feedback
·Do 10 more SQL problems at medium difficulty

2 weeks out

Behavioral polish and mock loops

·Rehearse every story out loud. Cut to 2-3 minutes each
·Run 2 full mock loops with a mid-level DE or coach
·Identify your 3 weakest behavioral areas and draft additional stories
·Review recent Airbnb news or earnings call for fresh talking points

Week of

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: interviewers want to find reasons to hire you, not to reject you
