While I cannot respond as a doctor, I can respond as an EMT. Totally different. But heres the deal.

The person who is the most important to you on the worst day of your life is the emt. The interview was literally "do you have a drivers license, and are you grossed out by stuff?" The rest you learned on the job.

Weird how doctors are vetted but prehospital folk are not.

edit yes there is training, but it happens after hire
