I was a state surveyor for a brief time back in 2014. The salary wasn't great, but the benefits---especially health insurance!---were awesome. We got a total of four weeks PTO, plus paid holidays (Columbus Day or the day after Thanksgiving and Christmas, anyone?). The health insurance was incredible; mine was free and my husband's coverage was only $70/month, and we had $15 co-pays for doctors' office visits and $5 meds...everything else was covered 95%. This was a lifesaver considering my husband was battling cancer and his meds were very expensive. I wish I could have continued on in that job, but it wasn't meant to be and I washed out of the training program within four months. (Now I'm on Medicare by virtue of being on Social Security Disability, and it's nowhere near the coverage I had then, but it's a whole lot better than nothing.)
As for what one can do to increase the chances of being hired, get lots of experience in the field you want to work in. For example, if you want to be a surveyor, you'll want to work in LTC for awhile and work different positions, like MDS nurse and DNS. The application process takes a while; you apply online and wait for someone to contact you for an interview. This may be as long as a few months. Then when you do interview, it's usually a panel interview, first with the managers and then with the managers and other surveyors. You have to project confidence and be able to think fast on your feet, because they will ask you all sorts of "what would/have you do/done in this or that situation" questions.
Good luck in your future endeavors, whatever you decide to do.
