Senior React Developer

This test targets senior-level React developers and combines advanced JavaScript logic challenges with React-specific coding and multiple choice questions. The React portion evaluates understanding of component structure, immutability, derived state, dependency resolution, and performance patterns using simulated props/state inputs. JavaScript questions ensure fluency in functional patterns, deep object/array manipulation, and algorithmic problem solving. The test is designed to filter candidates who can reason about large-scale component logic and write clean, production-grade code.
