Half the confusion in modern PM interviews comes from using Agile and Scrum interchangeably. They are not the same thing — and getting the distinction right makes you sound senior immediately.
What Agile is
A set of values and principles for iterative delivery. Agile is bigger than Scrum and predates it.
What Scrum is
A specific framework — sprints, roles, ceremonies — that implements Agile principles in software contexts.
Where each fits
Use Scrum when you have stable, cross-functional teams. Use Kanban (also Agile, not Scrum) when work flows continuously. Use neither if the deliverable is regulatory and serial.
The bottom line
Don’t marry a framework. Match the framework to the work — and explain why in your interview.
