My (unsuccessful) ER tech interview included a lot of "tell me about a time when you discovered that waiting for information before doing something was more important than doing something immediately." "Tell me about a time you disagreed with a superior."
My interviewer seemed particularly cognizant of two things:
1) most EMTs and paramedics want to do more than allowed in the hospital setting
2) average job duration for ER techs at that hospital was six-nine months, as most are on their way to nursing school or other career advancement
As a newly minted EMT with no health care experience, I was told they did not have enough experienced people to hire someone without experience at that time. (I may have just gotten a courtesy interview due to a doc friend who made a couple calls.)
I don't want to do transport EMS, so I've taken to applying to non-ER patient care tech jobs. However, they want CNAs for those. It's ridiculous that someone who's undecided between med and PA school would choose med because they couldn't find a hospital job, but it's helping a little. Hospital HR departments are a nightmare.
