It really depends per county. My county in Sacramento, I had to do a written test (the questions are from NR) a practical exam, and then after that I had my oral interview. After I passed my oral interview, I had to do a physical with the doctor, drug test, and had to do a strength test. I heard it wasn't hard, but it was 120 pounds! Thats basically lifting my body weight so it was a hard for me The other stuff though, (practical and written) were pretty smiple! Good luck!
