What should your CV include if you have no work experience?
Not having previous work experience does not mean that you do not have very important skills, values and competencies, and this is what you have to highlight.
You can follow the structure of a standard CV, but you will have to balance each section and give more importance to training, professional interests or soft skills (what you can contribute to the company due to your personality, qualities, competencies, etc.).

The CV of a person without work experience should always include a good summary (presentation), academic training, internships or volunteer work (if applicable), skills, availability, aptitudes and any other type of activity that you consider may be relevant to the job you are looking for.
Also, don't forget to tailor your presentation to the specific position you are applying for, highlighting the skills that are relevant to the company you are sending your CV to. For example, if you are applying for a position that involves dealing with the public, it is advisable to highlight that you are a "sociable, outgoing person who enjoys dealing with people." If, on the other hand, you are applying for an administrative position, you should highlight qualities such as responsibility, meticulousness or order.
