Practice problems
Spotify data engineer practice set
Spotify data engineer practice set, mapped from predicted domain emphasis. Tap into any problem to work it in the live environment.
Active Duo
The growth team is building a cross-engagement segment of users who both make purchases and log browsing sessions on the platform. Return a deduplicated list of usernames for users with activity in both areas.
Quantile Calculator
Given a list of numbers and percentile (0-100), return the value at that percentile using linear interpolation. The index is percentile / 100 * (n - 1); if fractional, linearly interpolate between the floor and ceiling indices of the sorted values.
Users Who Churned in February
Find all users who had sessions in January 2026 but none in February 2026.
The Gaps Between
A data-quality job profiles raw record exports before they load into the warehouse, and the records are dicts that don't all carry the same columns. For every column that appears in any record, report how many records hold a real value versus how many are blank, where blank means the value is `None` or the column is absent from that record entirely. Each column maps to its own `null_count` and `non_null_count`, and an empty batch produces an empty result.
Rolling 7-day active users
Count distinct users active in the trailing 7 days for each date. Product analytics staple.
Carry the One
In grade-school subtraction you scribble a mark each time you borrow. Recover those marks.

The loop
How the interview actually runs
01Recruiter screen
45 minLonger than many peer companies. Spotify wants to understand motivation and squad fit, their squad model means team-specific chemistry is real.
- →Research the squad: Discovery, Podcasts, Personalization, Marketplace
- →Streaming + music + cultural context is genuinely a signal, don't pretend not to care
- →Ask about squad autonomy. Spotify's squad model is core culture
02Technical phone screen
60 minSQL + a product analytics scenario. 'A key metric dropped 10% yesterday. Figure out why.' Spotify assesses analytical thinking alongside SQL fluency.
- →Practice drill-down analysis: segment by platform, country, cohort, time of day
- →Be explicit about your investigation order. Spotify interviewers watch it
- →Know music-specific metrics: MAU/DAU, stream-through rate, skip rate
03Onsite: data system design
60 minDesign a streaming-data pipeline. Music play events, podcast engagement, recommendation feedback loops. Spotify's scale is music-data-specific (billions of streams/day).
- →Event-stream architecture is central: Kafka + Flink or similar
- →Discuss exactly-once semantics for billing/royalty systems
- →Recommendation feedback loops: feature stores, real-time scoring
04Onsite: squad fit + behavioral
60 minBlend of technical deep-dive and cultural fit. Spotify's squad model means team chemistry is assessed as much as individual capability.
- →Collaboration stories within squads, autonomy matters
- →Spotify's 'we belong' mantra, inclusive culture stories land
- →Stories about prioritizing squad autonomy over centralized standards
Level bar
What Spotify expects at L4 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.
Spotify-specific emphasis
Spotify's loop is characterized by: Squad-based engineering, product analytics depth, streaming-data specialization. Calibrate your preparation to that, generic FAANG prep will not close the gap on company-specific expectations.
Behavioral
How Spotify frames behavioral rounds
Playful
Spotify's culture values creativity and experimentation. Engineers who take themselves too seriously stand out negatively.
Collaborative
Squad model depends on cross-role collaboration: engineers, data scientists, product managers working tightly.
Innovative
Spotify's product is built on novel experiences (Discover Weekly, Wrapped). Engineers are expected to bring new ideas, not just execute.
Passionate
Cultural alignment with music, podcasts, and audio matters. Engineers who clearly use the product deeply are valued.
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, Spotify weights this round heavily
- ·Read Spotify'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+ Spotify-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 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
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 Spotify 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: interviewers want to find reasons to hire you, not to reject you

FAQ
Common questions
- What level is Data Engineer at Spotify?
- Data Engineer maps to L4 on Spotify's engineering ladder. This is an individual contributor level; expectations focus on shipped production pipelines end-to-end and can debug them when they break.
- How much does a Spotify Data Engineer make?
- Based on 19 offer samples covering 2022-2026, Spotify Data Engineer sees $203K at the 25th percentile, $216K at the median, and $230K at the 75th percentile, median base $175K and median annual equity $41K. Typical experience range: 3-7 years..
- How is the Data Engineer loop different from other levels at Spotify?
- The rounds look similar, but the bar calibrates to seniority. Data Engineer is evaluated on shipped production pipelines end-to-end and can debug them when they break. Questions at this level probe production pipeline ownership and on-call debugging.
- How long should I prepare for the Spotify Data Engineer interview?
- Plan for 6-8 weeks of prep if you're already a working DE. Under 4 weeks rushes the behavioral prep, which takes the most time.
- Does Spotify interview data engineers differently than software engineers?
- They differ meaningfully. Spotify's DE loop has heavier SQL, replaces the general system-design with a data-specific one (pipelines, warehouse design), and expects production data ops experience.
