Transforming Blocking Calls with Mono?

Answer
Use Mono.fromCallable and subscribeOn. Frame the concept in practical terms so you can explain it during interview discussion.
Blocking calls can be wrapped in a Mono using Mono.fromCallable and then offloaded to a different scheduler with subscribeOn to prevent blocking the main thread. This pattern is useful for integrating legacy blocking APIs into a reactive system, such as a slow database driver in an e-commerce platform.
