Yes! Remember how long it took you to complete AMCAS and secondary applications? It takes us (admissions) a long time to read through everything plus letters of recommendation. I just came from a national meeting and saw many of my admissions friends and screening is the #1 pain point for admissions teams. Many of us don't have armies of screeners like some undergraduate admissions offices and the med school application is way more indepth than the Common Application. The bottomline is, with small admissions teams this just takes time.
