Pros
It was a great way to learn medical terminology and meet different types of medical providers and learn about the field more in general. I highly recommend this position to any pre-health students.
Cons
I think it definitely depends on what clinic or hospital you are working in. I worked full-time over summers in different IM or FM clinics which was a little more laid back. During school, I worked part-time in the ER which was significantly more stressful. Hours could vary a lot and I pulled a lot of unexpected 12 hour shifts when it was originally 8 hours, which can be difficult with school. A drawback more specific to my location were the politics, many providers made their scribes uncomfortable with certain remarks and it was a reason a lot of people did not stay for very long.
