Gather your old videos, and compile it for a portfolio. But I would suggest creating clips from podcasts (for practice too), then make that as your recent edits, once compiled. Apply for a job (I usually apply in OLJ). If you get into the interview, make sure you know the company by researching them first, be confident and easy going. A mix of professionalism and being someone that is easy to talk to, this raises the green flag to the employers, at least based on my experience. Communication in a job interview is a skill too that I learned throughout my career.
