This year was a challenge. If a program has 500 applicants and each application takes 10 minutes to review, that's basically 2 weeks of full time reading. Presumably most programs split that up between several people, but it's a challenge. And this year ERAS opened several weeks late, giving programs even less time to review. So sure, "it's the job" - but there are limits.
I wouldn't worry. Even if application review to pick interviews was somewhat superficial, we then have lots of time to do a deeper review prior to your interview itself. Any problems like this get sorted out.
