Preparing for my first interview in 10 months after 3 years as an IT help-desk technician

It has been 10 months since my last interview and I feel rusty. This is my first time dealing with any of this. The role is similar to my old job as an IT help-desk technician. What calms you down?

Thanks for writing this out. I went through something close to it 10 months ago, and it got easier once I kept a simple log of every call and form.
