Will my career be viewed negatively?

Hi guys, hope all is well and thank you in advance for your insight!

I am 27 years old, and have worked as a pharmaceuticals sales rep for the last three years. I call on ophthalmologists, and spend every day interacting with physicians—either in their office or surgery center. I thought this would be beneficial to my application, but have come across some opinions as of late that disagree. Will my career be seen positively or negatively?

Can I use the hours on the job spent shadowing physicians in clinic or in surgery as shadowing hours? Should I get experience shadowing physicians from different specialties?
