Shopify Data Scientist Interview Questions
Shopify's data scientist process runs a recruiter screen, a take-home or live SQL/stats assessment, a case study on a merchant or growth metric, and onsite rounds on experimentation and cross-functional collaboration.
What to Expect
| Round | Format | Focus | Difficulty |
|---|---|---|---|
| Recruiter screen | 20-30 min | Background, motivation, role scope | Low |
| SQL/stats assessment | 45-60 min | SQL queries, probability/statistics fundamentals | Medium-High |
| Case study | 60-90 min | Analyze a merchant growth or churn metric and recommend action | High |
| Onsite/cross-functional rounds | 30-45 min each, 2-3 total | Experimentation design, communicating with product and engineering | High |
Prep time: 2-3 weeks — practice SQL joins/window functions and A/B testing fundamentals, and be ready to discuss e-commerce-specific metrics like GMV, churn, and merchant retention.
Sample Questions and How to Approach Them
- "Merchant churn increased 3% this quarter. How would you investigate?" Segment by merchant size, tenure, and plan tier before hypothesizing causes, and check for seasonality effects common in e-commerce.
- "Write a SQL query to find merchants whose GMV dropped more than 20% month over month." Talk through the self-join or window function logic clearly.
- "How would you design an experiment to test a new checkout feature's impact on conversion?" Cover the primary metric, guardrail metrics (page load time, error rate), and sample size considerations.
- "Tell me about a time your analysis directly influenced a product decision." Emphasize the business action taken as a result, not just the analysis itself.
- "How do you decide which merchant segment to prioritize for a retention campaign?" Discuss weighing segment size against churn risk and expected lifetime value.
- "How do you communicate a null or inconclusive experiment result to a product team eager to ship?" Show you can hold the line on evidence while still being constructive about next steps.
