I can't give you to much info on the written test and the skills test. (I skipped all of these)
They seem to be pretty easy and from what I heard, they are starting to let things slide just because they need so many EMTs and to many of them were failing. Interview is also simple. Answer honestly and always add something at the end of the interview. Usually to summarize why you are a great candidate.
Now, the physical portion. They usually put you on a treadmill at the beginning just to get you warmed up. It's a cycling machine, not a treadmill (my apologies)
After that i believe you go straight to lifting weights up and down 3-steps for a total of 3 times. The most you have to lift is 120 or 140 pounds in a crate, can't remember. You can't place these weights down during the test or it's an automatic fail. Last part is a back testing machine. Best way to pass is to Push hard and fast. If you want to start training for it. Hyper extensions at home would be ideal.
I believe that's all they have. Let me know if you have other questions.
