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.

The Revenue That Was Wrong for Two Weeks

Our transformation layer has grown to over 200 models, and we're seeing silent data quality failures slip into production reports. The data team wants a pipeline design that enforces quality gates, prevents bad models from promoting downstream, and gives analysts confidence in the output. Design the pipeline.

The Talent Funnel

A job marketplace tracks candidate activity from the moment a job listing is viewed through to an accepted offer. The analytics team needs to measure funnel drop-off rates at each stage, compare conversion by job type and location, track time-to-hire by company, and attribute sourcing channel credit. Design a schema that supports all of this.

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.

London, UK

Meta in London

Largest European DE market. Comp is materially lower than US metros but higher than anywhere else in Europe. Visa sponsorship is routine for senior roles.

Meta pays about 35% less in London than its reference band; this maps to local market compensation norms. Meta sponsors visas for staff data engineer hires in London as a matter of course. The interview loop itself is identical to Meta's global process in London; local variation shows up in team and compensation.

The loop

How the interview actually runs

01Recruiter screen

30 min

Non-technical. The recruiter confirms level, product area (Ads, Integrity, Instagram, Reality Labs), and motivations. How you describe past work signals IC3/IC4/IC5.

→Quantify everything: row counts, daily event volumes, TB processed
→Research the specific team. Meta has dozens of DE teams with different tech stacks
→Ask whether the loop includes a Python round; some teams do, some don't

02Technical phone screen

45 min

Live SQL coding, 1-2 problems, in a shared doc with no syntax highlighting. Problems emphasize window functions, multi-step logic, and event-stream schemas.

→Think out loud from the start, silence worries the interviewer
→Expect window functions: ROW_NUMBER, LAG, LEAD, running totals
→Ask clarifying questions: NULL handling, duplicates, timezone of timestamps

03Onsite: SQL deep-dive

45 min

2-3 SQL problems with increasing complexity. The last often adds an optimization discussion: 'Your solution works, now make it efficient on 500B rows.'

→Practice writing SQL without autocomplete. Meta uses a shared doc
→When discussing optimization, mention partition pruning, predicate pushdown
→Use CTEs to break complex queries into readable steps

04Onsite: Python / data manipulation

45 min

Practical data work, not LeetCode. Parse JSON logs, transform nested structures, write a data validation function, build a small ETL step.

→Practice file I/O, dictionary manipulation, list comprehensions
→Write helper functions instead of one monolithic block
→Handle edge cases explicitly, empty inputs, missing keys, malformed data

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

Level bar

What Meta 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.

Meta-specific emphasis

Meta's loop is characterized by: SQL-heavy with fast-paced coding expectations and a product-sense orientation. Calibrate your preparation to that, generic FAANG prep will not close the gap on company-specific expectations.

Behavioral

How Meta frames behavioral rounds

Move Fast

Meta's culture rewards shipping and iterating. Stories about shipping a V1, measuring, and iterating land harder than stories about getting a design perfect before launch.

“Tell me about a time you shipped something before it was ready.”

Focus on Long-Term Impact

Paired with Move Fast. Meta wants DEs who ship fast without creating 3-year tech debt. Balance matters.

“Describe a decision where you chose long-term quality over short-term velocity.”

Build Awesome Things

Meta wants people who care deeply about craft. Your ETL pipeline is not just a job, it is a thing you built.

“What's a data system you've built that you're proud of?”

Live in the Future

Senior and above: betting on the technology curve. Candidates who talk about where data infrastructure is going in 3 years land strongly.

“How do you expect data engineering to change in the next 3 years?”

·Identify your 3 weakest behavioral areas and draft additional stories
·Review recent Meta 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
·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
