The interview process began with an initial screening, leading to a pair programming round with two engineers. I successfully completed the core coding task, but some of the test cases were not satisfied. Regrettably, my candidacy did not proceed to the subsequent interview stage.

We have a web client that makes requests to Service B and Service C. If either service fails 3 times within 10 minutes, we should stop making requests to that service for 5 minutes (circuit breaker open). After 5 minutes, we should try again (circuit breaker half-open/closed).

We need to implement this logic in the WebClient.execute(Request) method.
