Start by clarifying the problem and constraints, then implement a straightforward solution before refactoring for readability and efficiency. Proactively identify edge cases and write your own tests to validate correctness, explaining your reasoning throughout.
Pro tip: Treat the refactoring and edge-case testing as a chance to demonstrate code quality and thoroughness—Stripe values clean, maintainable code and attention to detail. Verbally walk through your test cases to show you think like a user, not just a coder.
Ask clarifying questions about input ranges, expected outputs, and constraints. Outline your approach and choose data structures, mentioning trade-offs.
Write a correct, straightforward implementation first. Focus on getting a baseline solution that passes basic cases, even if not optimal.
Improve naming, extract functions, remove duplication, and optimize if needed. Explain why each change improves readability or maintainability.
List edge cases such as empty inputs, single elements, duplicates, large inputs, and invalid types. Modify code to handle them gracefully.
Create test cases covering normal, edge, and error scenarios. Run them mentally or with code, and discuss expected vs. actual results.

Went 3 for 3 on the integration part so nothing to complain about there.
Start by clarifying the specific integration scenario and the components involved, then walk through the API contract and data flow step by step. Use a concrete example to illustrate how the components interact, covering both happy path and error handling. Emphasize idempotency, versioning, and observability to show production readiness.
Pro tip: Demonstrate familiarity with Stripe's API design principles by mentioning idempotency keys, webhook signature verification, and versioned endpoints—these are core to Stripe's ecosystem and signal you understand real-world integration challenges.
Ask clarifying questions to understand the specific integration context, such as the components involved, expected scale, and any constraints. This ensures your answer is relevant and shows you think before coding.
Describe the API endpoints, request/response schemas, and authentication mechanisms. Highlight how the contract ensures compatibility and how versioning is handled.
Explain the sequence of interactions between components, including synchronous calls, asynchronous events (e.g., webhooks), and data transformations. Use a diagram or step-by-step narrative.
Discuss how to handle failures, retries, idempotency, and timeouts. Mention monitoring and logging to detect and debug integration issues.
Recap the key points and invite feedback or questions to ensure alignment. This shows collaboration and attention to detail.
