Practice problems
Databricks senior data engineer practice set
Practice sets surfaced for Databricks senior data engineer candidates by the same model that reads their job postings. Each card opens a working coding environment.
All Infra Regions
Return DISTINCT region values from infra_nodes as a single column.
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.
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.
Auth Service Health Checks
Return every column of every svc_health row where svc_name equals 'auth-svc' exactly.
Classic DE round opener. Window function + partition. Edit to tweak the threshold.
The loop
How the interview actually runs
01Recruiter screen
30 minDatabricks hires heavily for Spark + Delta Lake expertise. The recruiter probes depth in these specific technologies.
- →Spark experience on any cloud is weighed heavily
- →Mention Delta Lake or Apache Iceberg experience
- →Customer-facing DE roles (CSE, Field Engineering) have different tracks
02Technical phone screen
60 minSpark-focused coding. Expect optimization questions, partition-skew handling, broadcast vs shuffle decisions, Delta Lake merge semantics.
- →Know Spark physical plan reading, it comes up constantly
- →Delta Lake specifics: MERGE semantics, Z-ordering, time travel
- →Be ready to write PySpark or Scala Spark fluently
03Onsite: Spark deep-dive
60 minAdvanced Spark: solve a performance problem on a 10 TB dataset, debug a stuck job from metrics screenshots, or design a Delta Lake schema for a specific workload.
- →Physical plan, shuffle analysis, partition skew are table stakes
- →AQE (Adaptive Query Execution) is hot at Databricks, know what it does
- →Delta Lake internals: deletion vectors, liquid clustering, checkpoints
04Onsite: architecture
60 minDesign a lakehouse-oriented pipeline. Databricks expects candidates to reach for Delta Lake, Unity Catalog, and medallion architecture natively.
- →Bronze-silver-gold pattern is the default
- →Unity Catalog for governance and lineage
- →Discuss the lakehouse vs warehouse debate with nuance
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'
Level bar
What Databricks 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.'
Databricks-specific emphasis
Databricks's loop is characterized by: Spark-and-Delta-deep technical expectations, customer-facing engineering mindset. Calibrate your preparation to that, generic FAANG prep will not close the gap on company-specific expectations.
Behavioral
How Databricks frames behavioral rounds
Customer-focused engineering
Databricks sells to data teams. DEs are expected to think about the customer experience even when not customer-facing.
Raise the bar
Databricks operates in a hiring market where 'hire above the median' is explicit. Candidates should show they've made their previous teams better.
Go fast with high quality
Databricks ships frequently to enterprise customers where bugs are expensive. Speed + quality is a real cultural tension.
Be open and direct
Databricks leadership emphasizes direct communication. Avoiding hard conversations is a negative signal.
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, Databricks weights this round heavily
- ·Read Databricks'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+ Databricks-style problems in their domain
- ·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 Databricks'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 Databricks 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

FAQ
Common questions
- How much does a Databricks Senior Data Engineer make?
- Databricks Senior Data Engineer offers span $297K-$419K across 18 samples from 2021-2026, with a median of $363K, median base $156K and median annual equity $152K. Typical experience range: 7-10 years..
- How is the Senior Data Engineer loop different from other levels at Databricks?
- Senior Data Engineer loops run the same stages as other levels, but interviewers calibrate difficulty to independent technical leadership and cross-team influence, especially around independent system design and cross-team influence.
- How long should I prepare for the Databricks Senior Data Engineer interview?
- 8-10 weeks is the standard window for a working DE. Less than 4 weeks almost always means cutting the behavioral prep short.
- Does Databricks interview data engineers differently than software engineers?
- The tracks diverge. DE at Databricks weights SQL and pipeline-design rounds, and interviewers expect specific production data experience that SWE loops don't probe.
