The Water Collector

Given a list of non-negative integers representing wall heights, find two walls (by index) that together with the x-axis form a container holding the maximum amount of water. Water volume between walls at i and j is min(heights[i], heights[j]) * (j - i). Return that maximum volume.

The Retail Tables That Need a New Home

You are given an existing transactional database from a retail operation covering orders, customers, products, stores, and employees. The analytics team cannot write performant queries against this structure. Redesign it as a dimensional warehouse that supports reporting on sales performance, product mix, and customer behavior.

Consumer Goods Trade Promotion Pipeline on GCP

We are a consumer goods company running dozens of trade promotions simultaneously across hundreds of retail partners, and our commercial analytics team needs to measure promotion ROI in near-real time to see which promotions are working and which are wasting money. Right now the data is fragmented across retailer portals, our own ERP, and third-party syndicated data providers. Design the ingestion pipeline and the BigQuery analytics architecture.

Machine Process Event Log Schema

We collect structured logs from a fleet of machines. Each machine runs many processes, and we need to track when each process runs and how long it takes. Data scientists need to query metrics like average elapsed time per process and plot process timelines across machines. Design the data model, and describe how you'd load this data via an ETL.

Chicago, IL

Google in Chicago

Trading firms (Citadel, Jump, Jane Street) compete aggressively for DEs. Enterprise tech (McDonald's, United, Walgreens) also hires locally.

Google pays about 18% less in Chicago than its reference band; this maps to local market compensation norms. The interview loop itself is identical to Google's global process in Chicago; local variation shows up in team and compensation.

The loop

How the interview actually runs

01Recruiter screen

30 min

Level calibration and team matching. Google hires at a level and then matches you to a team post-offer, so the loop is generic even if the recruiter names a specific team.

→Be flexible about team. Google teams are assigned after offer
→Ask about the 'generalist pool' vs specific-team interview path
→Have specific examples of scale: queries per second, petabytes, users served

02Technical phone screen

45 min

Coding problem in a shared doc. DE candidates see SQL + a small algo problem. The algo problem tests CS fundamentals, not LeetCode hard.

→Practice SQL on Google-scale schemas: ad impressions, search logs, YouTube view events
→For the algo portion, arrays/strings/hash maps cover 80%, trees and graphs are rarer for DEs
→Explain time/space complexity explicitly

03Onsite: SQL + coding

45 min

Two interviewers, usually split between SQL deep-dive and algorithms. DE loops weight SQL heavier than SWE loops.

→Explicit about indexing and query-plan assumptions even though Google uses BigQuery, not indexed databases
→Know window functions cold. Google SQL loves them
→For algorithms, think out loud about brute force first, then optimize

04Onsite: Data infrastructure design

45 min

Design a large-scale data system. BigQuery, Dataflow, Spanner, Pub/Sub are common prompts. Google loves asking you to design a subset of their own infrastructure.

→Know Google's own stack at high level: BigQuery, Dataflow, Spanner, Colossus, Bigtable, Borg
→Discuss consistency, partition tolerance, and latency explicitly
→Cost and scalability framing land well. Google interviewers think at planet scale

05Architecture strategy

60 min

At staff level, system design expands to multi-system strategy: 'Design the data platform for a 500-person org' or 'We have 40 pipelines producing inconsistent output; how do you fix it?' The evaluator watches for whether you think about developer experience, tech-debt paydown, and multi-quarter roadmaps.

→Talk about teams and processes, not just technology
→Name the specific mechanisms you would create (code review standards, shared libraries, data contracts)
→Be ready to defend why not to build something you would build at senior level

06Googleyness + leadership

45 min

Behavioral round testing collaboration, humility, comfort with ambiguity, and user focus. The hiring committee weights this round heavily.

→Googleyness is not a joke, humility and collaborative stories outrank hero-mode stories
→Prepare examples of navigating ambiguity and working cross-functionally
→Have a user-obsession story, even if your 'user' is another internal team

Level bar

What Google expects at Staff Data Engineer

Technical strategy ownership

Staff DEs set technical direction for multiple teams. Interviewers ask 'What tech decisions have you influenced across your org?' and probe depth: how did you socialize it, who pushed back, what trade-offs did you accept?

Multi-system design

Staff-level design is not one pipeline; it is the platform that 10 pipelines run on. Think data contracts, metadata stores, standardized ingestion patterns, shared orchestration, and the tradeoffs between standardization and team autonomy.

Tech-debt and migration leadership

Stories about leading a multi-quarter migration: the plan, the phasing, the stakeholder management, the rollback criteria. Staff DEs are expected to have shipped at least one such effort.

Mentorship scale

At staff, mentorship goes beyond 1:1 coaching: you have influenced hiring rubrics, run tech talks, or built onboarding that accelerated new hires.

Google-specific emphasis

Google's loop is characterized by: Classic CS fundamentals with a Googleyness round and a hiring committee making the final call. Calibrate your preparation to that, generic FAANG prep will not close the gap on company-specific expectations.

Behavioral

How Google frames behavioral rounds

Googleyness

A cultural fit signal for collaboration, humility, and openness. Heavily weighted by the hiring committee.

“Tell me about a time you received critical feedback and acted on it.”

Navigating ambiguity

Google problems are rarely well-specified. They want engineers who can decompose vague goals into concrete milestones without hand-holding.

“Describe a project where the requirements were unclear and you had to define them.”

User focus

Even for internal DE work, Google expects candidates to think about the downstream user (an analyst, a product team, a consumer).

“Tell me about a time a stakeholder's request didn't match their actual need.”

Collaboration across teams

Google scale means every DE project touches multiple teams. Stories about influence without authority score high.

“Describe a situation where you worked with another team that had a different priority than yours.”

·Do 20+ Google-style problems in their domain
·Time yourself: 25 min per medium, 35 min per hard
·Record yourself narrating approach aloud, communication is graded

4 weeks out

Platform-level system design

·Design 3-5 multi-system platforms: metadata store, shared ingestion, governance layer
·Prepare 2-3 stories where you drove technical direction across teams
·Practice mock interviews with another staff+ engineer
·Review Google's publicly described platform work for recent architectural shifts

2 weeks out

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

·Review recent Google news or earnings call for fresh talking points

Week of

Taper and logistics

·No new content. Review your notes only
·Sleep. Mental energy matters more than one more practice problem
