Fivetran is the dominant managed ELT (extract-load-transform) platform — automated data integration from hundreds of sources into modern warehouses. The interview emphasizes data engineering, schema evolution, change-data-capture (CDC), and the realities of building reliable connectors against unstable third-party APIs.
Process
Recruiter screen → 60-minute coding phone (medium DSA) → onsite virtual: 2 coding, 1 system design, 1 craft deep-dive, 1 behavioral. Cycle: 3–4 weeks.
What they actually ask
- Design a CDC-based connector for a transactional database (Postgres, MySQL)
- Design schema evolution: source adds a column, downstream queries should not break
- Design a connector framework that handles rate limits and incremental sync
- Coding: medium DSA with parsing or data-transformation framing
- Behavioral: ownership, customer focus, technical writing
Levels and comp (2026)
- SE II: $160K–$200K total
- Senior SE: $230K–$300K
- Staff: $330K–$430K
- Principal: $450K–$580K
Prep priorities
- Be fluent in Java (the bulk of the connector platform) and one scripting language
- Understand database internals: WAL, replication slots, binlogs
- Read about modern data stacks: Snowflake, BigQuery, Redshift, dbt
Frequently Asked Questions
Is Fivetran remote-friendly?
Hybrid in Oakland, Denver, Bangalore, and others. Many engineering roles are remote within supported countries.
How does Fivetran compare to Stitch or Airbyte?
Fivetran is the broadest commercial offering with strong enterprise traction. Airbyte is open-source. Stitch (Talend) is older and more limited. Fivetran pays best.
What is the bar like?
Strong fundamentals with practical engineering. Less LeetCode-hard, more “can you build a robust system.”
