Interview / Pre-employment Test

Sorry if this is in the wrong place.

Tomorrow, I have my first professional interview and I am a bit nervous.

I am a social person and I have heard that I interview well.

BUT, I am really really nervous on if I get the job about the Pre-employment test.

Any advice would be greatly appreciated! The test are EKG (I was a MT for 3 years), Blood Gas, basic knowledge assessment test, and medication test.

The floor is an CM-ICU. Cardiac Floor.

Again any advice, please...
