The Interview Process

Data/SQL Assessment

A take-home or live test where you must extract specific insights from a relational database and visualize the findings.

Technical Screen

Review of your assessment, followed by questions on statistical methodology, A/B testing frameworks, and data visualization tools (Tableau, Python).

Business Application Panel

Focuses heavily on how you translate complex data into plain English for non-technical stakeholders (e.g., marketing or customer service leaders).

Real Vanguard Interview Questions

Practice these exact questions faced by previous Data Analyst / Data Scientist candidates.

1We want to run an A/B test on a new feature in the Vanguard mobile app designed to encourage users to increase their monthly 401(k) contributions. Walk me through the exact statistical methodology you would use to determine if the test was successful. (A/B Testing / Statistics)

2Write a SQL query using window functions to identify the top 10% of Vanguard clients based on their total asset growth over the last 5 years. (SQL Data Manipulation)

3Tell me about a time your data analysis revealed a truth that the business team fundamentally did not want to hear. How did you present your findings? (Clarity / Courage)

4How would you build a predictive model to identify retail clients who are at a high risk of moving their assets to a competitor (churn)? What features would you select? (Applied Machine Learning)
