I freeze in interviews, tips? - any advice?

It has been 12 months since my last interview and I feel rusty. 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.

Thanks for writing this out. I went through something close to it 12 months ago, and it got easier once I kept a simple log of every call and form.
