When a Cover Letter Is Required
- The job posting explicitly asks for one
- The application system has a cover letter upload field
- You are applying through email (attach it)
- A recruiter or contact specifically requests it
- You are applying to executive or senior positions
- Academic and government positions almost always require one
When It Is Optional but Recommended
- The posting says "optional" -- write one anyway to stand out
- You have a referral or connection at the company
- You are changing careers and need to explain the transition
- You have employment gaps or other circumstances to address
- You are applying to a competitive position
Studies show that 83% of hiring managers say a good cover letter can convince them to interview a candidate whose resume alone would not have been enough.
When You Can Skip It
- The job posting explicitly says not to include one
- The application system has no way to upload one
- You are applying through LinkedIn Easy Apply with no attachment option
- High-volume entry-level positions where cover letters are not reviewed
Benefits of Writing a Cover Letter
- Shows genuine interest in the specific company and role
- Allows you to address concerns (gaps, career changes)
- Demonstrates communication skills
- Provides context that a resume cannot
- Sets you apart from candidates who skip it
