Senior
6 rounds
Updated 6/25/2026

Meta's Data Analyst interview process for senior-level candidates consists of a comprehensive evaluation spanning 6 rounds over 3-4 weeks. The process combines initial phone screenings with structured onsite interviews assessing technical SQL expertise, product analytics capability, A/B testing and experimentation design, and behavioral competencies. Each round isolates specific dimensions: technical accuracy, analytical reasoning, product intuition, experimental rigor, and cross-functional collaboration. Senior-level candidates are evaluated not just on task execution but on strategic thinking, mentorship capability, and ability to influence product decisions through data-driven insights.

Frequently Asked Data Analyst Interview Questions

SQL-Based Data Validation and Anomaly DetectionEasyTechnical
28 practiced
Write a single PostgreSQL query that produces a column-level data quality summary for the table sales with schema: sales(sale_id INTEGER PRIMARY KEY, customer_id INTEGER, sale_amount NUMERIC, sale_date TIMESTAMP, promo_code VARCHAR(20)). For EACH column return: total_rows, null_count, null_pct, distinct_count, invalid_count (for sale_amount treat negative values as invalid), and up to three example_invalid_values. The query should be one statement and use standard SQL features.
Trade Offs Between Metrics and GuardrailsMediumTechnical
21 practiced
Create a short rubric (3-5 dimensions) for deciding which guardrails should be enforced as hard stops versus soft warnings during product launches. Describe each dimension and provide an example mapping.
Cross Functional Collaboration and CoordinationHardSystem Design
48 practiced
As the organization scales, ad-hoc data requests are crippling the analytics team. Propose a scalable operating model that balances speed and quality: describe team structure (centralized vs. federated), intake and prioritization processes, tooling and self-serve capabilities, KPIs for the analytics function, and a transition plan that minimizes disruption.
Metric Frameworks and Goal AlignmentHardTechnical
31 practiced
Causal inference (hard): Your team launched a loyalty program and observed a revenue increase, but multiple marketing campaigns ran in the same period. Outline an observational causal inference strategy (e.g., difference-in-differences, synthetic control, matching) to estimate the program's incremental effect. Describe required data, assumptions, and diagnostics to validate results.
Metrics and KPI FundamentalsEasyTechnical
53 practiced
Using PostgreSQL, write a query to compute conversion rate from 'signup' to first 'purchase' within 14 days for each signup cohort day. Given events(user_id, event_name, occurred_at TIMESTAMP, is_test BOOLEAN), exclude test users and ensure each user is counted once in numerator and denominator. Describe your approach and assumptions.
Data Investigation and Root Cause AnalysisEasyTechnical
47 practiced
Define a structured process for data investigation and root cause analysis that you would follow when diagnosing a sudden change in a business metric (for example: a 20% drop in weekly active users). Include the end-to-end steps from validating the signal (is it real vs noise) through data-quality checks, decomposition and hypothesis generation, diagnostic queries, qualitative follow-up, and how you would communicate concise recommendations and artifacts (dashboards, reproducible queries, tickets).
A and B Test DesignMediumTechnical
43 practiced
Two teams launch overlapping experiments on the same user population and features that may interact. Describe experimental designs, analysis techniques, and governance policies to handle overlapping experiments safely (e.g., orthogonal assignment, exclusion rules, factorial design). Include operational suggestions to reduce accidental conflicts.
SQL-Based Data Validation and Anomaly DetectionMediumTechnical
45 practiced
Implement a SQL query that computes the percentage change in total revenue between today and the same weekday last week, and returns an alert row if the absolute percent change > 25% OR absolute dollar change > 10,000. Assume a table sales(sale_date DATE, revenue NUMERIC). Show the query and how you would protect against division by zero.
Cross Functional Collaboration and CoordinationMediumTechnical
45 practiced
You discover a systematic data quality issue that affects KPIs used by multiple teams. Describe how you would communicate the problem to stakeholders, coordinate the cross-functional remediation plan (including short-term mitigations), run a root-cause analysis, and set preventative controls to avoid reoccurrence.
Metric Frameworks and Goal AlignmentHardTechnical
34 practiced
Decomposition and ownership mapping (hard): Provide an example mapping that decomposes a company's North Star (monthly active customers who pay) into per-team signals with explicit ownership and one leading indicator per team. Cover at least three teams (onboarding, search/discovery, checkout) and explain why each signal helps the team influence the North Star.
