add two promises core interview pattern Pattern
1 problems
Pattern pages help build reusable solving frames. Identify signals first, then explain state, transition, and edge handling.
Recognition Signals
- Check if the candidate demonstrates an understanding of promise resolution order.
- Look for efficient handling of asynchronous behavior and edge cases.
Solve Flow
- 1. Define the active state/window.
- 2. Update state while preserving invariants.
- 3. Validate with edge-heavy examples.
Common Misses
- Not properly handling the case where one promise resolves before the other, potentially causing issues with the addition.
