A resumen de trabajo is a formal document that summarizes your professional experience, skills, education, and achievements. Its main goal is to present your qualifications in a concise and compelling way that convinces employers to invite you for an interview.
Unlike a CV, which can be longer and more detailed, a resume is typically 1–2 pages and focuses only on the most relevant information.
Always customize your resume for each job application. Generic resumes are far less effective.
A strong resume follows a clear structure that makes it easy for recruiters to scan quickly.
| Section | Description |
|---|---|
| Header | Name, phone, email, LinkedIn |
| Summary | Brief overview of your experience |
| Experience | Work history with achievements |
| Education | Degrees and certifications |
