Here are some common follow-up questions you might encounter during an interview on Agile principles, with good responses:

1. "Can you provide an example of how you have applied Agile principles in a previous project?"

   • Good Response: "In my last project, we applied Scrum to deliver a customer-facing application. We held sprint planning meetings to break down the project into manageable tasks, and sprint reviews to showcase our progress. This iterative approach helped us incorporate customer feedback early and regularly, which significantly improved the final product quality."
