Google Data Engineer candidates report a recruiter screen, SQL and Python coding, and data pipeline design. Some also describe LeetCode-style coding, behavioral rounds and team matching. Process details vary by candidate.

Candidates describe Google's Data Engineer interviews as practical, but the format varies a lot. Most start with a recruiter conversation about background and experience. After that, reports mention SQL and Python coding, data modeling, pipeline design, and in some cases LeetCode-style tree and graph problems.
SQL and edge cases come up repeatedly. One candidate who did not advance said the SQL round went beyond a working query and probed edge cases. Another reported non-trivial SQL plus analytical schema design, including normalization tradeoffs, partitioning, clustering and indexing. A third described advanced SQL in both a CoderPad technical screen and the onsite loop.
Pipeline design is the other recurring theme. One candidate who received an offer described designing a real-time clickstream or ad-click pipeline, covering batch versus streaming tradeoffs, idempotency, duplicates and late-arriving data. Another discussed designing an ETL pipeline from source to sink, with error handling and late or duplicate data. One senior candidate, early in the process, was asked how to handle 100 daily alerts, rising BigQuery cost and automated reports for 1,000 merchants.
Coding still matters. One candidate had two back-to-back easy-to-medium interviews on tree and graph traversal, and another was asked an islands-style question. Some candidates also reported Googleyness-style behavioral questions and team matching, where connecting your experience to the team's work mattered. Reports are mixed, so prepare for both coding-heavy and conversational loops, and ask your recruiter what your specific process includes.

Synthesized from candidate reports. Individual experiences may vary.
Candidates report an initial recruiter call centered on their background and past work. Reports describe it as non-technical. Be ready to explain concrete work and how it fits the role.
One candidate reports a CoderPad screen combining advanced SQL with Python data manipulation. Another, who did not advance, said the SQL coding round included edge-case questions. Practice explaining your reasoning aloud.
One candidate reports designing a real-time clickstream pipeline covering batch versus streaming, idempotency and late-arriving data. Another discussed ETL design with duplicates and error handling. Data modeling reports mention star schemas, slowly changing dimensions, normalization and partitioning. Exact rounds may differ by team and level.
One candidate described a five-round onsite covering data modeling, pipeline design, Python coding, advanced SQL and a Googleyness/behavioral conversation. Another had two back-to-back LeetCode-style interviews on tree and graph traversal. Formats vary, so confirm yours with the recruiter.
One candidate reports team matching after the technical rounds and matched with a team in a second matching round, which appeared to be the final stage. The conversations focused on knowing your resume in detail and connecting your experience to the team's work.
