My advice would be to speak to the current residents and see what they have to say about their rotations. Ask about their daily routines and staffing requirements. Also ask how confident/how well-prepared they feel staffing on their own. Regardless of almost every resident trying to be PC, if something is "off", it will show. I've come across residents who said they felt ready by December, and some that nervously chuckled, "well..." Obviously this will vary widely resident to resident, but if more than 1 at a particular program doesn't seem ready to staff on their own by this time, maybe the training is not adequate/rigorous enough.
You're right that some "big names" institution aren't as well-received as some other less well-known (nationally) local institutions when it comes to hiring pharmacy resident graduates. For example, when I went to interview for my job with a DOP, he said if resident from program X applied he would take that resident over others because of how rigorous their curriculum is (awkward moment - for me - as obviously I didn't come from program X 😛). But information like that is difficult to get a hold of - I didn't even know how well-received program X is locally until he told me. At this point, gauging current residents is probably your best bet.
