Databricks (the "Lakehouse" data/AI platform company) hires primarily for software engineering, data engineering, machine learning/data science, and technical field roles (Solutions/Resident Solutions Architects). Its interview process is described consistently across sources as a multi-week, multi-stage loop that is technically demanding (LeetCode medium-to-hard coding, distributed-systems/Spark depth, and a mandatory behavioral round). Databricks does not publish a single named "interview framework" the way Amazon publishes its Leadership Principles; instead, it has a publicly documented set of six company-wide "culture principles" that recruiters and interviewers say they evaluate candidates against, especially in the required behavioral round, though, importantly, Databricks' own interview-prep page does not itself say in writing that the behavioral round is scored against those six named principles (see evaluation_framework notes). Caveat: much of the granular detail below (exact question wording, exact round counts, use of CodeSignal vs. HackerRank/CoderPad, "hiring committee"/VP sign-off steps) comes from aggregated candidate reports (Glassdoor, Blind, interviewing.io, Exponent, LeetCode Discuss) and several SEO/AI-generated prep-guide sites (e.g., linkjob.ai, ophyai.com, prachub.com, prepfully.com) whose factual reliability is unverified; treat specifics as directionally accurate and role/team-dependent rather than official policy. Databricks' own careers page does name high-level phases of the process (identifying opportunities, applying online, connecting with Talent Acquisition, skill assessments, interviewing, reference checks, decision and offer) but does not publish exact round-by-round counts, interview names, or per-stage timing: that granular detail is reconstructed from candidate reports below.

The Process

  1. 1

    Recruiter / Talent Acquisition screen · ~30 minutes

    Initial call with a recruiter covering resume, background, motivation ('Why Databricks?'), and the specific team/role. Purely non-technical.

  2. 2

    Online assessment (new grad / intern roles) · ~70 minutes

    For SWE intern and new-grad pipelines, a proctored (webcam + screen recording) coding test on CodeSignal or HackerRank with roughly 3-4 problems (mix of easy/medium/hard) covering arrays, hashing, strings, graphs, and sometimes DP. This is described as a hard early filter; candidate reports note that even near-perfect scores don't guarantee advancement. Experienced-hire roles more often skip straight to a live phone screen.

  3. 3

    Technical phone screen · ~1 hour

    One live coding interview with an engineer, typically in CoderPad or a similar shared/runnable online IDE. Expect 1-2 LeetCode-style data-structures-and-algorithms problems at medium-to-hard difficulty, sometimes with SQL or Python-specific questions for data roles.

  4. 4

    Hiring manager screen · ~1 hour

    A call with the hiring manager for the specific team, primarily behavioral: background/experience walkthrough, what the candidate enjoys working on, and candidate questions about the org. Sometimes combined with or scheduled close to the onsite loop rather than as a separate stage.

  5. 5

    Virtual onsite loop · 4-5 hours total, split across 4-5 one-hour sessions

    The core evaluation, usually run virtually over Google Meet across one or two days. Commonly reported composition for SWE: 2 algorithms/coding rounds (one may lean toward a specific domain deep-dive, e.g. Spark internals, distributed systems, or a single-component design with pseudocode), 1 concurrency/multithreading coding round (repeatedly flagged by candidates as its own dedicated, notably hard round), 1 system design round (often conducted collaboratively in a Google Doc rather than a whiteboard tool), and 1 cross-functional/behavioral round. ML/Data Scientist and Data Engineer loops swap one coding round for ML system design, pipeline debugging, or statistics questions relevant to the role. Solutions Architect loops add a take-home or live technical exercise plus a panel presentation pitching a solution to a simulated customer.

  6. 6

    Reference checks · Several days to ~1 week

    Typically 2-3 references (a manager plus senior colleagues) are contacted; multiple sources describe references as weighted heavily in the final call, sometimes deciding between similarly-scored candidates.

  7. 7

    Hiring committee / final decision · Several days to ~1-2 weeks

    Candidate reports (not confirmed by Databricks' own materials) describe a hiring-committee-style review of interview feedback, career trajectory, and references, followed by senior engineering leadership (e.g., a VP of Engineering) sign-off on some roles; multiple independent candidate threads describe being rejected at this stage despite a clean interview loop. Treat this stage's existence and structure as well-corroborated by aggregated candidate anecdotes but not officially documented by Databricks.

Evaluation Framework

Databricks Culture Principles (official, company-wide, not a formal numbered interview rubric, but the closest publicly documented equivalent)

We are customer obsessedWe raise the barWe are truth seekingWe operate from first principlesWe bias for actionWe put the company first

Independently verified: these are exactly the six culture principles currently published verbatim, in this order, on Databricks' official 'Our culture' careers page (databricks.com/company/careers/culture); the original draft's list and count were correct with no additions or omissions needed. Important precision fix: Databricks' separate official interview-prep page (databricks.com/company/careers/interview-prep) does NOT name these six principles anywhere; it only says behavioral interviews assess 'how you work, learn, collaborate and navigate challenges' and that 'every candidate is evaluated against the same core competencies, creating an objective and level playing field,' using prompts like 'Tell me about a time...', 'Describe a situation...', 'Give an example of...', and 'How do you...?' The mapping from the six named culture principles to specific behavioral prompts (e.g., 'truth seeking' -> a time data changed your mind) is a reasonable, coach-recommended inference, not something Databricks states explicitly in writing anywhere public. Databricks does not publish a separate named technical competency framework (nothing analogous to Amazon's Leadership Principles list with per-question tagging); technical rubrics referenced by candidates (coding, system design, concurrency, domain depth) appear to be informal/team-specific rather than a published company standard. Some third-party prep sites also describe behavioral evaluation dimensions of 'collaboration, conflict, ownership, ambiguity, and communication under pressure'; these are candidate-report characterizations, not an official Databricks-named framework, so they are presented here as descriptive color rather than a second framework.

Sample Interview Questions

Coding / Data Structures & Algorithms8 questions
  • Design a Hit Counter / rate limiter that tracks requests over a rolling time window

  • Implement atoi / String-to-Integer conversion with edge-case handling
  • House Robber (and the circular-houses follow-up, House Robber II)
  • Convert an IP address to CIDR notation (or the reverse) given a range of addresses; a related variant asks you to design an IP-based allow/deny firewall using ordered CIDR rules

Concurrency & Multithreading5 questions
  • Implement an efficient logger/queue that processes messages from multiple producer threads safely
  • Design a thread-safe rate limiter or counter shared across concurrent requests
  • Implement a producer-consumer pattern with bounded buffer and proper synchronization
  • Explain and resolve race conditions in a given snippet of multithreaded code
  • Discuss trade-offs between locks, atomics, and lock-free structures for a shared-state problem (e.g., why isn't a plain HashMap thread-safe, and how does a ConcurrentHashMap solve it)
System Design (data-platform flavored)6 questions
  • Design a service that finds customers the cheapest copy of a book across multiple distributors (search + purchase flow)
  • Design a real-time data ingestion pipeline (e.g., streaming events into a lakehouse)
  • Design a Spark job that processes terabytes of data every 10 minutes on Databricks: discuss partitioning, shuffles, and fault tolerance
  • Design core components of a system like Delta Lake (transaction log, ACID guarantees, schema evolution)
  • Design a distributed file system, or a data lake supporting both streaming and batch writes
  • Given a single component (e.g., a metadata cache or query scheduler), go deep on concurrency, data structures, and pseudocode rather than whiteboard architecture boxes
Machine Learning / Data Engineering depth (role-specific)7 questions
  • Design an end-to-end ML pipeline that handles large datasets and automates training and deployment
  • How do you know when a deployed model needs to be refreshed or retrained? How do you detect drift?
  • Explain the difference between classification and regression, and when you'd choose each
  • Walk through diagnosing a Spark job with skewed partitions or a slow shuffle stage
  • Explain the Medallion (bronze/silver/gold) architecture and why you'd structure a pipeline that way
  • When would you use Spark SQL vs. the DataFrame API for a given transformation?
  • Explain ROC vs. precision-recall trade-offs, or diagnose issues in a linear regression (data-scientist-leaning loops)
Behavioral / Cross-functional8 questions
  • Tell me about a time you had a conflict with a coworker and how you resolved it
  • Describe a project you're most proud of and why
  • Tell me about a time you changed your mind after seeing new data (maps well to 'truth seeking')
  • Tell me about a time you raised the bar on quality or pushed for a higher standard
  • Tell me about a time you had to solve a problem without all the necessary information (ambiguity)
  • Tell me about a time you took initiative on a problem instead of waiting for someone else to address it
  • Tell me about a time you received difficult feedback from a manager and how you responded
  • Why Databricks? What about this specific team/role interests you?

Coach's Tips

Prepare for a genuinely dedicated concurrency/multithreading coding round: this is one of the more distinctive and consistently-reported parts of the SWE loop (implementing a thread-safe logger, rate limiter, or producer-consumer queue) and candidates repeatedly flag it as the hardest round; most generic LeetCode grinding under-prepares for it.

The system design round is often run collaboratively in a Google Doc rather than a whiteboard tool, and leans toward data-platform problems (ingestion pipelines, lakehouse/Delta-style storage, Spark job design) rather than generic 'design Twitter'-style prompts; rehearse writing clear, typed-out requirements and trade-off discussions, not just diagrams.

Take the behavioral round seriously: it shows up in every loop, and Databricks' own interview-prep page says every candidate is measured against 'the same core competencies' probing how you work, learn, collaborate, and navigate challenges. Databricks doesn't publicly draw an explicit line from those interview questions to its six culture principles (customer obsessed, raise the bar, truth seeking, first principles, bias for action, put the company first), but those principles are the company's own stated values, so it's smart prep to have STAR-format stories ready that map cleanly onto at least 'truth seeking' (a time data changed your mind) and 'raise the bar' (a time you pushed for a higher standard).

If applying to a new-grad or intern role, budget serious prep time for the proctored CodeSignal/HackerRank online assessment (~70 minutes, 3-4 problems); multiple reports say it is a harder filter than the later phone screen, and a good-but-not-perfect score can still eliminate strong candidates.

Because the loop commonly runs 4-7 weeks (longer for staff/principal roles, and Glassdoor's own aggregate average across all roles is around 5 weeks) and includes weighted reference checks plus a hiring-committee-style review, line up 2-3 strong references early and give them a heads-up on what the role/team actually needs, rather than scrambling after the onsite.

Domain fluency matters more here than at a typical generalist tech company: be ready to speak concretely about Spark internals (shuffles, partitioning, query planning, caching), Delta Lake, and (for ML/DE roles) MLflow, Unity Catalog, and the medallion (bronze/silver/gold) architecture, since interviewers reportedly probe past the surface answer on these topics.
