Interview-ready summary

If they ask:

“How do you orchestrate logic in Mule?”

You can answer:

“For conditional routing I'd use Choice. For repeated record processing I'd distinguish between sequential For Each and Parallel For Each depending on ordering and downstream capacity. For several independent operations on the same request, Scatter-Gather can reduce latency by running routes concurrently and then aggregating the results. I keep reusable responsibilities in subflows invoked through Flow Reference, and I avoid parallelizing dependent writes or assuming that cross-system operations are transactional.”

That is a very solid Mule developer answer.
