I freeze in interviews, tips? after 11 years as an IT help-desk technician

It has been 6 months since my last interview and I feel rusty. I would rather hear the honest version than the polite one. I want to come across as confident and honest. What calms you down?

I record myself on my phone and listen back. The second try is always better than the first.

Ask about the first ninety days. It shows you are thinking about the work.
