Cover Letter
A one-page letter accompanying your resume that explains why you're applying, why you're a strong fit, and what specifically drew you to this company and role. Strong cover letters add context that resumes can't — they're not required everywhere but matter when they are.
A cover letter is a one-page (typically 3-4 paragraphs, 250-400 words) document submitted alongside your resume. It addresses the hiring manager directly and answers questions your resume can't: why this company, why this role, why now. Cover letters are increasingly optional — many applications mark them as 'optional,' and for roles receiving hundreds of applications, many recruiters don't read them. But in several scenarios they're critical: - **Career changers**: Explaining why you're pivoting and how your background transfers - **Gaps in employment**: Briefly addressing a gap before it becomes a source of speculation - **Referrals**: Mentioning who referred you and why you're excited about the company - **Small companies and startups**: Where culture fit matters more and hiring is more personal - **Creative and writing roles**: The cover letter itself is a writing sample Structure of a strong cover letter: 1. Opening: Specific hook (not 'I am writing to apply for...'). A result, a connection to the company, or a direct statement of fit. 2. Body: Two paragraphs connecting your specific experience to specific requirements in the JD. 3. Closing: Confident call to action, not a pleading request. Generic cover letters (where you swap out the company name) almost always read as generic. Hiring managers can tell.
Why it matters
When cover letters are reviewed, they're often the deciding factor between two equally-qualified finalists. A great cover letter can elevate a slightly weaker resume; a generic one can disqualify a strong one.
Candidate tip
Write your cover letter's opening sentence last — make it specific to the company (referencing a product, announcement, or mission statement) so it can't possibly be mistaken for a template.
