After working in the industry for two years, I can say two points: companies either want a highly skilled professional in one area or someone with a variety of skills who is versatile and can adapt to any kind of role in the company. Apart from having an internship or a list of projects, I think its important that your resume points to a direction in the biomedical field. It is good to have experience in different areas: instrumentation, tissue engineering or programming using MATLAB, but I think it gives a clear picture to the hiring manager if all the projects or experience point a certain direction like one specific area or one of many areas coinciding with the main profile of your resume. Conferences and workshops, being a part of or creating a biomedical blog are also some of the ways to showcase your skills as a biomedical engineer.
