Frequently Asked Questions

Expert answers to common cover letter questions

Do I really need a cover letter for every job application?

While not all employers require cover letters, including one significantly increases your chances of getting noticed. Our research shows that 63% of recruiters read cover letters when making interview decisions. Even when listed as 'optional,' a well-crafted cover letter can set you apart from other candidates. The exception might be for very high-volume applications or when using automated application systems, but for targeted applications to companies you're genuinely interested in, always include a personalized cover letter.

How long should a cover letter be?

The ideal cover letter length is 3-4 short paragraphs, totaling 250-400 words, and should never exceed one page. Recruiters spend an average of just 23 seconds reading cover letters, so conciseness is crucial. Focus on your most relevant achievements and how they directly relate to the role. Each paragraph should have a clear purpose: opening hook, 1-2 body paragraphs with specific examples, and a strong closing with call to action.

Should I mention salary expectations in my cover letter?

Generally, avoid mentioning salary expectations in your cover letter unless specifically requested in the job posting. Cover letters should focus on your value proposition and fit for the role. Salary discussions are better left for later in the interview process when you have more leverage. If the employer specifically asks for salary requirements, address it briefly and consider providing a range based on market research, or state that you're open to discussing compensation based on the complete package.

How do I write a cover letter when I don't have much experience?

Focus on transferable skills, relevant coursework, projects, internships, volunteer work, and personal qualities that align with the role. Emphasize your enthusiasm, willingness to learn, and any relevant achievements even if they're from academic or non-professional settings. Use specific examples to demonstrate problem-solving abilities, leadership potential, or technical skills. Research the company thoroughly to show genuine interest and explain why you're passionate about the industry or role despite limited experience.

Can I use AI to write my cover letters?

AI can be an excellent tool for generating cover letter drafts and overcoming writer's block, but the key is using it strategically. AI-generated cover letters work best when you provide specific details about your experience, the role, and the company. Always review and personalize the output to ensure it sounds authentic and accurately represents your voice. Use AI as a starting point, then add your personal touch, specific examples, and genuine enthusiasm. Our AI Cover Letter Generator is specifically designed to create personalized, human-sounding letters that pass both ATS systems and human review.
