Meta Data Analyst Interview Preparation Guide (Mid-Level, 2026)

Data Analyst
Meta
Mid Level
6 rounds
Updated 6/16/2026

Meta's Data Analyst interview process for mid-level candidates (2-5 years experience) spans 4-6 weeks and consists of a structured progression evaluating technical proficiency, analytical thinking, product intuition, and cultural alignment. The process includes recruiter screening, hiring manager discussion, phone-based technical assessments, and multiple onsite interviews covering SQL/data manipulation, analytics and metrics design, product experimentation, and behavioral competencies. For mid-level analysts, Meta expects demonstrated ownership of projects end-to-end, ability to navigate ambiguity independently, cross-functional collaboration skills, and mentoring capability with junior team members.

Frequently Asked Data Analyst Interview Questions

Cross Functional Collaboration and CoordinationMediumTechnical
48 practiced
How would you build a six-month analytics roadmap that balances urgent stakeholder requests, foundational data-platform work, and longer-term measurement projects? Describe your prioritization framework, how you would collect stakeholder input and trade-offs, and the communication plan to share progress and changes.
Experimental Design and Analysis PitfallsHardTechnical
32 practiced
Metrics in your experiment (e.g., pageviews, session duration, conversion) are correlated. How would you account for correlation when testing multiple metrics and reporting results? Discuss multivariate testing (e.g., MANOVA), combining metrics into a composite, and adjustments that account for dependencies (effective number of tests or hierarchical testing).
Query Optimization and Execution PlansEasyTechnical
89 practiced
Explain in detail the difference between a sequential table scan and an index scan. For a table with 50 million rows and a predicate that matches approximately 1% of rows, what factors influence whether the optimizer picks a Seq Scan or an Index Scan? As a data analyst, how would you check which choice was made and why?
Data Cleaning and Quality Validation in SQLMediumTechnical
87 practiced
You need to find likely duplicate customer rows using fuzzy matching on name and email. Given:
customers(id INT, name TEXT, email TEXT, phone TEXT)
Write a PostgreSQL query using pg_trgm similarity() or levenshtein to return candidate pairs with name similarity >= 0.8 OR email similarity >= 0.9. Describe the pros and cons of this approach and how you would tune thresholds to balance precision and recall for deduplication.
Decision Making Under UncertaintyMediumTechnical
73 practiced
You have partial telemetry from 2 of 5 regions. Outline a probabilistic method to estimate global error rate and confidence intervals. Describe either a bootstrap approach or a Bayesian hierarchical model and list the steps and data transformations you would implement in SQL/Python to produce an estimate stakeholders can act on.
A and B Test DesignHardTechnical
62 practiced
You ran an experiment that produced wide confidence intervals and high metric variance, yielding an inconclusive result. Create a structured diagnostic checklist to find root causes across data, metric engineering, randomization, and segmentation. For each likely cause, propose remediation steps and how you would validate the fix.
Cross Functional Collaboration and CoordinationHardTechnical
42 practiced
Design an evaluation plan to measure the long-term (12+ months) business impact of a multi-team feature rollout. Include experimental or quasi-experimental designs, counterfactual construction, required data sources, power and sample-size considerations, and how to communicate uncertainty and assumptions to executives.
Experimental Design and Analysis PitfallsMediumTechnical
33 practiced
You are designing an experiment for a subscription product with high churn and limited sample availability. Propose a primary metric (for example 7-day retention vs trial-to-paid conversion), justify your choice based on signal-to-noise and business relevance, and list guardrail metrics and how you'd estimate minimum detectable effect for the chosen metric.
Query Optimization and Execution PlansEasyTechnical
71 practiced
Given the following Postgres EXPLAIN (ANALYZE, BUFFERS) output snippet for a reporting query, identify the single most expensive operator, explain why it appears in this plan, and list two quick mitigation steps you would try as a data analyst.
Hash Join  (cost=1000.00..5000.00 rows=100000 width=64) (actual time=200.00..450.00 rows=95000 loops=1)
  Hash Cond: (orders.customer_id = customers.id)
  -> Seq Scan on orders  (cost=0.00..3000.00 rows=500000 width=48) (actual time=0.02..150.00 rows=500000 loops=1)
  -> Hash  (cost=700.00..700.00 rows=100000 width=24) (actual time=180.00..180.00 rows=100000 loops=1)
        -> Seq Scan on customers  (cost=0.00..700.00 rows=100000 width=24) (actual time=0.01..40.00 rows=100000 loops=1)
Answer should reference cost and actual times and explain practical steps you would take next.
Data Cleaning and Quality Validation in SQLMediumTechnical
92 practiced
Explain how to implement row-level data lineage using only SQL constructs: capture source_file, source_row_id, ingestion_batch_id in staging, propagate these fields through transformations, and provide a sample SQL pattern that joins a transformed analytics row back to its originating source rows for root cause analysis. Use example table names: staging.raw_events and analytics.daily_events.
