Networking and co-op/internships play are important. as per my experience, as a MS student coming from a BS in bio, taking a diverse courseload can be very useful in narrowing your list of potential careers in BME. Because my undergraduate background was not in engineering I was strongly encouraged to take graduate level materials and programming courses in my first year. while i haven’t had the opportunity to work in the industry as of yet, I have a nice list of tasks that i know i don’t/wont enjoy. this has significantly narrowed my focus for the types of Co-ops and jobs that I apply for. I understand the importance of getting my foot in the door, however once your in, it helps if you know where you want to go next.
