No, your resume doesn’t need to be one page. Typically, high school students, college students, and young professionals with less experience will have a one page resume. However, if you have acquired more relevant work experience and education and you can’t fit it all onto one page, you will need to expand onto a second page.
Keep in mind, employers only spend about six seconds scanning your resume, so you want to keep everything as succinct as possible. Therefore, it’s important to only keep what’s relevant on your resume, and exclude anything that’s not related to your current career goals.
