Call the facility about 8 pm and ask the reception person who should be contacted.
Just FYI - some LTC places are part of big chains and they have a central recruiter with a 1-800 number. You can get that # from reception. And for the other LTCs, it'll vary between DON, HR, occasionally a recruiter, or someone else (I was once Staff Dev and I got the applications). Usually the bigger the facility, the more specific and sophisticated it is.
