Question normal

I am a current fourth yr medical student and in the process of interviewing for a residency position in Emergency Medicine. As I begin thinking about a non-traditional career path in either administration, business (healthcare consulting, pharma, insurance), and/or policy I was hoping for some advice on how to connect with mentors in those fields from an earlier point in residency. Also, what kind of things should I being doing during residency to secure competitive employment in the field I decide to pursue? Thank you
