Describe in your own words synchronous and asynchronous interactions. Provide examples from your work.

Synchronous interaction is when one party waits for the other party to complete an operation before continuing work. For example, when calling a function that returns a result, the calling thread is blocked until a response is received.

Asynchronous interaction is when a request is sent, but the caller does not wait for a response and continues working. The response is processed later, for example, through a callback, Promise, or event.

Work example:

• Synchronous: when integrating with an internal API, where I need to get data and process it immediately, I used synchronous HTTP requests to ensure the sequence of actions.

• Asynchronous: when working with message queues (e.g., RabbitMQ), I sent tasks for processing and did not wait for the result immediately, but processed them as they arrived, which increased system performance and fault tolerance.
