A portfolio is a collection of your best and most sophisticated works in any field. It should highlight the process of design and make stress on your strongest works. So the headhunters understand your experience, skills, and stage of development as a professional.
One of the most important things about a UX portfolio is that the document should explain in detail the process of creating the project. It allows hiring managers to see the stages of your works and your train of thought.
Remember, that's very important to know who is going to read your portfolio, and we're going to guide you through the process of UX portfolio creation both for a job application and other purposes.

Block format for information is what your portfolio needs, whether is a Web or PDF one. Formatting also matters, it should be clear, without excessive details, and easy to read. Remember, that the more engaging your portfolio is, the more chances you'll get noticed and get a job!
Feedback is also an important part of the UX design portfolio creation: before publishing/sending a portfolio, ask the opinion of your colleagues, and afterward, when publishing one, analyze the feedback of the recruiters: whether it's searchable or not, easy to read, if the structure is okay or not.
