SOLVERE?

hi fellow nurses, i have a quick question, that is even though solvere offers you the job, is it likely that you will be denied the job at the prisons in anyway? assuming you have clean background and at no fault of yours?,how long before you start working and does the prison's give you an interview? i guess i just want to know if you are guaranteed the job once solvere calls(or even any other prisons agency) you? thanks guys, i'n an LVN
Thanks and reply plz.
