This is mainly for the 3rd years applying next year, but many competitive EM applicants with low interview numbers oftentimes have one of following problems:
1. They applied all over the place but only included a few local programs.
-Example: From the midwest but applied to only a few midwestern programs and a ton of places down south and out west because "I'm tired of the winters."
2. They applied only to programs in highly desirable big cities on the coasts.
-Example: Only applying to popular locations like WA, OR, CA, TX, FL, NC, VA, NY, MA because "I don't want to live in flyover country."
This is in addition to some applicants being a little "cocky" and not applying to enough safeties (new programs and community programs). Now, this does not apply to everyone and some people just get unlucky some years (and others do actually have red flags in their applications). But, that being said, the above 2 reasons are a common theme with applicants who end up having a below average number of interviews or don't get most of their interviews till later in the season. Either way like I said before I wouldn't start worrying till November.
