• Query Optimization – Understanding how to write efficient queries on massive datasets, avoiding costly operations like unnecessary subqueries or cross joins.
• Advanced concepts (less common) – Recursive CTEs, complex regular expressions for string manipulation, and handling semi-structured data formats like JSON within SQL queries.

Example questions or scenarios:

• "Write a query to calculate the rolling 7-day average of data volume processed per connector type."
• "Given a table of user login events, write a query to identify sessions where a user performed more than five actions within a ten-minute window."

Business Case Analysis

This evaluation area tests your ability to apply data analysis to real-world business challenges. You will be given a scenario representing a typical Fivetran business problem and asked to walk through your diagnostic process.

Be ready to go over:

• Metric Definition – Designing key performance indicators (KPIs) that accurately reflect product health and customer success.
• Root Cause Analysis – Systematically isolating variables to explain anomalies in data trends or pipeline performance.
• Data-Driven Decision Making – Translating analytical findings into concrete recommendations for product or engineering teams.

Example questions or scenarios:

• "Our database connector churn rate increased by 15% this quarter. Walk me through how you would investigate this trend and present your findings."
• "How would you design an experiment to test whether a new user onboarding flow increases the activation rate of trial accounts?"

Behavioral & Peer Collaboration

This section assesses your communication style, your ability to handle feedback, and your alignment with Fivetran's core values. The hiring manager will spend significant time understanding your past experiences and how you navigate team dynamics.

Be ready to go over:

• Stakeholder Management – How you handle competing priorities and communicate analytical limitations to non-technical partners.
