Which describes a flow interview?

A flow interview refers to a running instance of a flow. When a user starts a flow, either through an action on a record, a button click, or an automated process, that specific execution of the flow becomes a flow interview. Each interview captures the current state of the flow, including any variables set, the user inputs provided, and the path taken through the flow, which can differ from other interviews of the same flow.

This concept is crucial for understanding how flows operate in Salesforce, as multiple interviews can run concurrently or sequentially, each representing unique user interactions or data handling. This makes tracking and managing the execution of flows essential for ensuring that processes are running smoothly and reliably.
