Advice on choosing a position

I'm a first yr nurse grad, and it has been difficult finding an RN position. I got hired doing POOL at a LT/skilled facility in the fall. I was grateful for the job. They were considering me for a position FT nights in early Dec, they just had wanted to see what the weekend charge RN thought about my performance. Only I never got the chance, the DON hired someone else. I guess I was "not quite ready". Boy was that a crush, I was feeling great up till then. I then got offered a job with DOC, just waiting for my background check to clear. While I am waiting they offer me back the position because the girl has put in her notice. I have not heard anything bad from the nurses that work at the DOC, in fact I have gotten a couple I love it! Now I have to decide. The LT or Dept of Corrections? Anyone with knowledge of DOC I would greatly appreciate! Now to go do my list of pros and cons of each.
Do the one until the other is a lock. They were not loyal to you so if the better offer comes along in a month go for it.
Go with the Dept. of Corrections. That other job dumped you when someone else came along. They might decide to do that to you again in the future. How does that saying go? Fool me once shame on you. Fool me twice shame on me.
Has anyone ever worked for Metro West Medical Center? I was offered a position but I want to check with some experienced nurses before I make a final decision...any help is appreciated!
