I had 0 shadowing hours, was not a scribe, did not have clinical employment, and was accepted to 4/5 schools I interviewed at (and WL turned A at the other one). I also had very significant, very unique experience in a different way, so that's why my application wasn't trashed at every school, but I'm sure there were a lot of schools where it wasn't given a second glance because of that. I wonder if I would have gotten into my dream school, who values shadowing highly, if I'd had some. If you do not have something EXTREMELY SIGNIFICANT to prove that you know you want to be a physician outside of shadowing/scribing/clinical employment, your chances of acceptance are incredibly slim. Not saying you absolutely cannot get in - as many have mentioned here, everyone knows of an outlier or two. Everybody thinks they'll be the exception...but with something as easy as shadowing, that almost all applicants have, you don't want to be the person in the pile that sticks out. I wish I had found SDN earlier and had the guidance to realize how important it is, but my advisor sucked and I trusted that she knew what she was doing. If I'd known before I applied, I absolutely would have taken a gap year to get shadowing. I know it's frustrating, but you all need to set yourselves up for success and make sure you have the strongest app you possibly can, unless you're willing to spend thousands of dollars two years in a row and have the disadvantage of being a reapplicant next year.
Not necessarily saying this directly to you, OP. It sounds like your job may suffice. I'm just saying, as someone who could be the reason that a school has a 99% rate instead of 100%, that I absolutely regret it and strongly advise against it.
