Frequently Asked Data Analyst Interview Questions

KPI Frameworks and GovernanceMediumTechnical
70 practiced
How should KPIs be aligned with OKRs? Provide a concrete example: one company OKR, the primary KPI you would track, three supporting KPIs, cadence for OKR reviews, and an escalation plan if the OKR is off-track mid-quarter.
Data Cleaning and Quality Validation in SQLMediumTechnical
96 practiced
Design SQL-based alert rules for critical data quality checks and categorize severity. For example: null_rate(order_date) > 5% = HIGH, row_count drift > 2% = MEDIUM, ingestion lag > 60 minutes = HIGH. Provide sample SQL that computes the current status for these three rules against an orders ingestion metadata table, and describe when an alert should escalate from email to on-call paging.
Complex Joins and Set OperationsEasyTechnical
72 practiced
Explain the differences between INNER JOIN and LEFT JOIN. Provide a concrete example (two small tables) where using LEFT JOIN returns rows with NULLs from the right table. As a Data Analyst, describe a reporting scenario where you would choose LEFT JOIN over INNER JOIN and why.
Advanced SQL Window FunctionsHardTechnical
62 practiced
Given a heavy GROUP BY query that is network-bound in a distributed data warehouse, explain how replacing part of the GROUP BY computation with window functions might reduce data movement. Provide a concrete example where computing per-partition aggregates with window functions reduces shuffle compared to a full GROUP BY + join.
A and B Test DesignHardTechnical
60 practiced
In an experiment you evaluate 20 metrics across engagement, revenue, and technical guardrails. Explain practical approaches to control false discoveries at the metric level while preserving power: hierarchical testing, metric families with corrections, pre-specification and gating, and how to implement these in a policy for an analytics team.
Hypothesis Testing and InferenceMediumTechnical
51 practiced
You're testing a rare event: conversion rate is around 0.1%. Describe analysis approaches that increase power and produce valid inference (e.g., Poisson or binomial modeling, aggregated testing, use of exact tests). Explain trade-offs.
Dashboard and Data Visualization DesignHardTechnical
76 practiced
Design an approach to visualize a product co-purchase network with millions of nodes and tens of millions of edges so merchandisers can find product clusters and cross-sell opportunities. Discuss backend aggregation (supernodes), graph sampling, progressive loading, layout algorithms, edge bundling, and user interactions like search, filters, and focus+context. Explain performance trade-offs.
Learning Agility and Growth MindsetEasyTechnical
58 practiced
You're asked to become proficient in SQL window functions to improve time-series reporting. Outline a 2-week learning plan with daily goals, practice exercises (including sample query ideas), and milestones you would use to demonstrate competency to your manager.
Data Cleaning and Quality Validation in SQLHardTechnical
89 practiced
A long-running DQ query joins three 200M-row tables and times out. As a data analyst, outline step-by-step SQL and infrastructure optimizations to reduce runtime under 30 minutes: consider rewriting the query, pre-aggregation, avoiding wide joins, partition/clustering keys, materialized views, using approximate functions, and leveraging warehouse-specific features. Provide concrete SQL rewrite examples where applicable.
Complex Joins and Set OperationsHardTechnical
82 practiced
For incremental ingestion of customer lists from multiple sources, compare using set operations (UNION/EXCEPT) vs multi-way joins for deduplication and enrichment. Which approach scales for streaming vs batch workflows? Provide sample SQL for an incremental MERGE/upsert approach and justify your choice for both streaming and batch.
