Is it Charleston County SC you are asking about????
If so you have to take and pass their tests before you interview. They will tell you the test is just like the NR test, it ain't. The NR test was easy.
Alot of folks don't make it past the test.
If you do make it in, it's not a bad place to work, the pay is good, and there are some great folks working there. Personally I wish they would stop trying to run it like the military, remember we're medical providers, not soldiers, and ease up on the uniforms. That button down, heavy polyester crap in the summer here sucks.
