Match Day is coming up. Here’s how medical students game the residency system
"Writing love letters
This is the most common way to game the match. Applicants send emails to residency program directors expressing their interest in the program, hoping to influence how the director ranks them. Applicants sometimes end up writing multiple letters professing their love to different programs. Sometimes, they tell more than one program director that their program is their first choice.
While programs often say that they don’t adjust their rankings based on “love letters,” some do. For one of my friends, a residency director for surgery told her, “the love letter could be a deciding factor in how we rank you.”
So, we’re stuck: If you don’t send one, it might look like you’re not interested."
