What to know before applying for jobs?

Hello everyone! I will be getting my license soon and applying for some jobs, mostly retail but I want to try for hospital as well. The thing is, it’s been about 7 months since I completed my training program, and I’m a little rusty (I couldn’t apply for licensure immediately after graduating since I wasn’t 18). I was wondering what I should brush up on before applying, and maybe what some good study resources might be. I am also aware I don’t have much of a chance to get a hospital job right away, but they are hiring for their outpatient pharmacy and I wanted to try. I did really well on my exam and in my course but I feel like I don’t remember most of it. Any advice would be appreciated!
