Plaid Interview Guide
22% easy, 60% medium, 18% hard · 15 problem suggestions · Arrays, Strings, Randomization
Overview
Plaid interviews focus on API design and data integration — the core of what Plaid does (connecting apps to bank accounts). The coding difficulty is moderate at 60% medium, but the system design rounds demand understanding of financial data APIs, security, and multi-institution integration. Plaid is smaller than PayPal or Stripe, so every interview round carries significant weight. The team is engineering-dense and values clean, well-documented code.
