Navigating HR Roles Without Certification: How Can I Prepare for Future Interviews?

I completed an MBA in Finance, but I am currently working as an HR Executive in a private organization. Recently, I attended an interview where they asked about my HR qualifications. However, I don't have any HR certificates. I am concerned that this issue may arise again in the future. How can I handle such situations, and could you please suggest any HR certification courses for me?
