What do I say about why I left my last job? after 7 years as a home health aide

They always ask why I left, and I freeze. I worked as a home health aide before this. I have been practising in the mirror. Do you mention numbers?

If a company has been in the news for layoffs, you can mention that. Often the interviewer already knows.

Keep everything in writing and save the confirmation numbers. It made the follow-up calls so much easier.
