Yes I hire for SNFs too and agree with what you have said above.
If there are multiple candidates mostly similar what I look for is the more engaging/outgoing person. When I tour them in the facility do they speak to and interact with the patients they pass or meet? Are the comfortable when doing this? How do they interact with staff they meet? I also try and weed out those who show they have a desire to work in a different setting but maybe are just looking for some good money in the SNF to start. Are all their clinicals OP or PEDs and they talk about how much they loved those? Or do they seem genuinely interested and wanting to work with older adults in SNF setting? It really sucks to hire the wrong person who leaves or doesnt work out. Costs a lot of time and money.
I had one PT candidate who had been working in PEDs but was now applying to work in SNF after a move. Right away I was a little suspicious if maybe she couldnt find a job right away in PEDs but she sounded like she wanted to get out of PEDs. However, I see on her resume she is going to be getting certified in aquatic therapy in a few months at a week long course. We are a SNF without a pool, so another red flag goes up, I ask her about this and she seems offended I would be concerned about the aquatic therapy cert and not impressed she was doing it. Newsflash, why would I be impressed you are spending a lot of time and money to get certified in something that you cant do at our facility if we hire you? Of course that will be a red flag that you may leave soon after to pursue that field.
