An interviewer can ask you to explain a workflow before asking you to build one. Start with the business population, then name the tool behavior that supports it. Saying that a workflow completed doesn't explain whether it kept the right records, used the intended type or preserved a missing-data exception.
These short questions cover sources, Results, filters, keys and simple preparation. Use the concrete record counts and field meanings in the prompt. There is no need to add a connector or enterprise feature that the situation doesn't require. Several wrong options describe a nearby tool with a different job. Explain that difference plainly and keep your answer tied to the evidence you could inspect in Designer. The checked choice is followed by the reason it fits.
