How long should your résumé be? It’s a long-standing debate among recruiters, but there is one thing they agree on: it needs to be relevant. This is true whether you're just out of school or have worked for 20 years, and it means your résumé needs to be concise and tailored to that job.
Recruiters won't read a full bulleted list of your duties and everything you did at every job. They only want to read what in your background is applicable to the particular job and/or company to which you’re applying. So your task is to make the information easily available.
