It really depends what you're interested in! In my experience, our practicum/preceptorship didn't affect the ability to find a job after graduation unless you want something very specific. If you want to start in a specialty, it would be helpful to have been exposed to it. In my case, I wanted to start in med/surg so I wanted my practicum to be different and let me see a different side of nursing. I chose pre-op/PACU.
