Confluent Software Engineer interview experience

After a short intro, I had to implement something like a registry: a register method to store functions, and a matching method that would return every function whose argument signatures fit what was provided. The tricky part was handling variadic behavior so that matches could work even when the inputs didn’t line up perfectly with a fixed signature.

As the problem progressed, I realized the key challenge wasn’t just getting the code to compile—it was organizing the matching logic so it could handle both regular fixed-arity functions and variadic ones cleanly. I walked through how I would
