First had a Zoom interview where the regional manager discussed the role and then asked me how to spell a few common medical terms, and asked for definitions. After she placed me with a site manager who administered a written test after a 2 week training module that went in depth on medical procedures and diagnosis we will see in the ED. Make sure to review the terminology and you should be good.

Casual but still formal with quiz that was known about beforehand plus typical interview questions. Asked about how I stay on task, why I want the job, and how long I expected to stay in this position.
