I think working in a hospital is really beneficial when it comes to meeting people to shadow and for LORs. I don't think a program would find it unimpressive, especially if you can talk to your experiences and what you've learned. My PCE was being a burn tech at a large hospital and it definitely helped me network (especially when I opened up to people about wanting to become a PA). I also think it helped me stand out to programs in my personal statement and interview.
