Databricks Interview Questions
The coding and system-design questions asked in Databricks interviews - with worked solutions, in-browser code execution, and active-recall review. 2 questions.
How Databricks interviews software engineers
Databricks runs a recruiter screen, a technical phone screen, sometimes a take-home, and a virtual onsite of four to six rounds, followed by hiring-committee review, references, and offer. Team matching can happen along the way.
Technical rounds go deep on systems: algorithms and data structures, but also concurrency, multithreading, I/O, and performance - reflecting the company's data-infrastructure focus. System design is often done collaboratively in a shared doc, and there is a hiring-manager round blending technical depth with behavioral fit.
The interview loop
- 1Recruiter screen~30 min on background, technical interests, and motivation.
- 2Technical phone screen~60 min on CoderPad - algorithms and data structures, sometimes SQL or Spark fundamentals.
- 3Take-home (sometimes)A practical assignment (advanced SQL or a Spark job), usually 48-72 hours, ~3-5 hours of work.
- 4Onsite panel4-6 one-hour rounds: coding, system design (often in a shared doc), systems programming (concurrency, performance), domain deep dive, and a hiring-manager / behavioral round.
What they look for
- Systems depth: concurrency, synchronization, I/O, and performance
- Strong algorithms plus practical data-engineering fluency
- Collaboration and conflict-resolution signal in behavioral rounds
How to prepare
- Go beyond LeetCode - revise multithreading, synchronization, and performance fundamentals.
- Brush up SQL and Spark basics if your role touches data infrastructure.
- Practice collaborative system design in a plain doc, talking through trade-offs.

Practice questions
- Music Player App(premium)
Design a Spotify-lite Android player - adaptive HLS/DASH streaming, gapless playback via the Media3 playlist API, background playback as a MediaSessionService that lights up Auto / Wear / lockscreen, offline downloads with Widevine DRM, audio focus, and resume-position persistence.
Mobilehard-2mo - Time-Based Key-Value Store(premium)
A key-value store with timestamped writes. Read at time t returns the latest value written at or before t; later phases add arbitrary-order inserts and range queries.
