Ajay's response provides a good example of a complex coding problem he solved using Kotlin, particularly mentioning the use of coroutines for performance optimization. However, the explanation could be clearer and more structured. Ajay could improve by outlining the problem, the steps taken to solve it, and the outcome more succinctly. Additionally, he could emphasize the impact of the solution on the project and how it contributed to his growth as a developer, as seen in the benchmark response.
