Frequently Asked Questions

How do I start a cover letter?

Start your cover letter with a strong opening that mentions the specific position you're applying for and where you found it. Include an attention-grabbing statement about your qualifications or enthusiasm for the role. For example: "As a digital marketing specialist with 5+ years of experience driving 200% ROI improvements, I was excited to see your opening for a Senior Marketing Manager at TechCorp."

What should I include in a cover letter?

A cover letter should include: 1) A professional header with your contact information, 2) The hiring manager's details and company address, 3) A compelling opening paragraph, 4) 1-2 body paragraphs highlighting relevant experience and achievements, 5) A paragraph explaining why you want to work for that specific company, 6) A strong closing with a call to action, and 7) A professional sign-off.

How long should a cover letter be?

A cover letter should be between 250-400 words and fit on a single page. This typically means 3-4 paragraphs. Keep it concise while including all essential information. Hiring managers spend an average of 7 seconds initially scanning a cover letter, so every word should add value.

Should I write a different cover letter for each job?

Yes, you should customize each cover letter for the specific job and company. Generic cover letters have a 75% lower response rate. Tailor at least 30% of your content to address the specific role requirements, company culture, and recent company achievements. This shows genuine interest and effort.

What's the difference between a cover letter and a resume?

A resume is a structured document listing your work history, skills, and education. A cover letter is a narrative that explains why you're the best fit for a specific role. While your resume shows what you've done, your cover letter explains how those experiences make you perfect for this particular position and company.
