The main goal is to get the recruiter interested in responding to your work and seeing you as a prospective job candidate. Your portfolio should clearly reflect your role in the company, define your role, list the main responsibilities and try to cover them in your portfolio. Find yourself a project to work on yourself, volunteer and offer your services to an organization that needs UX / UI design services. Add a narrative to your portfolio, where you acquaint the company with the project, telling what kind of project was created, why it was created and how many deadlines were on the designers.
