Data Engineer Interview Questions at Airbnb (2026 Guide)
Airbnb's data engineer interview centers on SQL depth, data modeling, and pipeline architecture across 4-5 rounds: a recruiter screen, a technical phone screen (SQL plus Python), and an onsite loop covering advanced SQL, data modeling/architecture, a behavioral round, and Airbnb's signature core values interviews. Difficulty is medium-high — the SQL bar is stricter than most FAANG loops, and Airbnb's internal data culture (Minerva metrics platform, Airflow origins) shapes the questions. Expect 4-6 weeks end to end.
Airbnb Data Engineer Interview at a Glance
| Stage | Format | Focus | Typical Length |
|---|---|---|---|
| Recruiter screen | Phone | Background, role fit | 30 min |
| Technical screen | Video + CoderPad | SQL, light Python | 60 min |
| Onsite: Advanced SQL | Live coding | Window functions, joins at scale | 60 min |
| Onsite: Data modeling | Whiteboard/video | Star schemas, warehouse design | 60 min |
| Onsite: Pipeline architecture | Discussion | Airflow-style orchestration, batch vs streaming | 45-60 min |
| Core values (x2) | Video | Mission and culture fit | 30-45 min each |
Note: Airbnb created Apache Airflow. Know it. Compensation for mid-level DEs is commonly in the mid-$200Ks to low-$300Ks total (estimate; level and location dependent).
Real-Style Questions by Round
SQL Screen
- Given bookings and listings tables, find the top 3 markets by month-over-month booking growth.
- Compute each host's rolling 90-day acceptance rate using window functions.
- Identify guests who booked in 3+ consecutive months.
Data Modeling
- Design the warehouse schema for Airbnb reservations, including cancellations and modifications.
- How would you model slowly changing dimensions for listing prices?
- Design a metrics layer so every team computes "nights booked" the same way.
Pipeline Architecture
- Design a daily pipeline that aggregates billions of search events into market-level demand signals.
- A critical DAG fails at 3 a.m. and downstream dashboards are wrong. Walk through detection, backfill, and prevention.
- Batch vs streaming for fraud signals on bookings — which and why?
- How do you enforce data quality checks in an Airflow pipeline?
Behavioral & Core Values
- Tell me about a data model you built that others disagreed with.
- Describe a time you found and fixed a silent data quality bug.
- Why Airbnb's mission over other companies?
How to Prepare
Drill window functions until they're reflexive — most rejections happen in the SQL rounds. Then rehearse modeling out loud. InterviewBoost.ai runs AI mock interviews tuned to data engineering loops, and Live Interview Assist suggests structured answers in 0.3 seconds during live Zoom, Teams, or Meet calls.

FAQs
What SQL level does Airbnb expect from data engineers? Advanced. Window functions, self-joins, and performance reasoning on large tables are standard.
Does Airbnb ask algorithm questions for data engineering? Rarely LeetCode-hard. Python questions lean toward data manipulation, not dynamic programming.
Is Airflow knowledge required? Effectively yes. Airbnb built Airflow; orchestration questions assume familiarity with DAGs, retries, and backfills.
How many rounds is the Airbnb data engineer interview? Usually 4-5: recruiter screen, technical screen, and a 4-6 session onsite including two core values interviews.
How long does the process take? About 4-6 weeks (estimate).
