← American Express Interview Insights
I went straight into features and kind of skipped the problem framing, which I regretted about two minutes in.
Start by clarifying the scope and goals of the reimbursement system, focusing on user pain points and business objectives. Then, outline a high-level design that covers key components like submission, approval, and payment, while addressing automation and integration. Finally, discuss trade-offs, success metrics, and cross-functional dependencies.
Pro tip: Emphasize how automation reduces manual errors and speeds up reimbursement, directly impacting employee satisfaction and operational efficiency. Also, highlight the importance of compliance and fraud detection, which are critical in financial services.
Ask questions to understand the scope: who are the users (employees, managers, finance), what types of expenses, what are the current pain points, and what are the business goals (e.g., reduce processing time, improve accuracy).
Identify key metrics such as reimbursement cycle time, error rate, employee satisfaction, and cost per transaction. These will guide design decisions and measure success.
Outline the main components: expense submission (mobile/web), automated policy checks, approval workflows, integration with accounting/payroll systems, and payment processing. Consider automation opportunities like OCR for receipts and AI for anomaly detection.
Discuss how to align with stakeholders: finance for compliance, IT for integration, legal for data privacy, and employees for usability. Highlight the need for clear communication and training.
Talk about trade-offs between automation and manual oversight, speed vs. accuracy, and build vs. buy. Address risks like fraud, data security, and change management.
