Yes, it's a good idea to have a resume even for your first job. A resume is a document that provides an overview of your education, skills, and work experience. Even if you don't have a lot of work experience yet, your resume can highlight your education, any relevant coursework or extracurricular activities, and any skills or qualifications you have that are relevant to the job you're applying for.

Having a well-written resume can help you stand out from other applicants and increase your chances of getting an interview. It shows that you're serious about the job and have taken the time to present yourself in the best possible way.

There are many resources available online to help you create a resume, and you can also ask for guidance from career services at your school or from a trusted mentor or family member.
