Yes, a resume needs a cover letter. While some companies don’t always request to see a cover letter, most employers prefer candidates to include one when applying for a job. The job market is competitive, and providing a cover letter sets you apart from other applicants.
Including a cover letter with your resume gives you a valuable opportunity to introduce yourself to the hiring manager and provide context to your application. On a cover letter, you can include skills and experience not listed in your resume, explain employment gaps, or even clarify when you’d be available for an interview and your willingness to relocate if you’re located far away from the company.
