I freeze in interviews, tips? - what worked for you?

It has been 12 months since my last interview and I feel rusty. I have read a lot of threads here and could not find my exact situation. I have practised answers but they sound stiff. How do you prepare answers?

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.
