Preparing for my first interview in 2 months after 7 years as a home health aide

I get tongue-tied when I am asked about my weaknesses. I worked as a home health aide before this. I have practised answers but they sound stiff. Any questions to ask at the end?

Arrive early, drink water and take a slow breath before you walk in. It sounds simple but it helps.

Prepare three stories with a clear beginning, action and result, and adapt them to the questions.
