They asked to bring a physical copy of the portfolio to the actual interview. I included my cover letter, resume, letters of recommendation, employee references, degree, license, BLS/ACLS, nursing scholarships and past certifications from other healthcare positions that I've held (CNA, Phlebotomy, Medical Assistant, etc)...pretty much in that order, I enclosed each document in a page protector and bound them inside a thin binder. I did not include a table of contents and kept the portfolio to maybe 10 to 12 documents total. Everyone is going to have a different portfolio and that is ok but it essentially includes professional documents related to your healthcare journey and the position you are applying for.
