How to write a cover letter that helps you secure interviews

In competitive job markets, a strong cover letter can play an important role in whether your application progresses to interview. While your CV sets out your experience and qualifications, your cover letter gives you the opportunity to explain why you’re a good match for the role and why an employer should want to meet you.

This guide focuses on how to use your cover letter to support shortlisting decisions, alongside practical advice on aligning it with your CV and online profile so your application works together as a whole.

What you'll learn in this guide:

This article is designed for candidates who understand the basics and want to improve their chances of being shortlisted. You’ll learn how to:

• Position your experience clearly against role requirements
• Align your cover letter with your CV and LinkedIn profile
• Avoid common mistakes that can weaken applications
• Write with the clarity and focus recruiters look for when shortlisting

How recruiters use cover letters when reviewing applications

Recruiters and hiring managers typically review cover letters alongside CVs, looking for quick signals that a candidate is worth progressing. In most cases, they are assessing:

• Relevance – how closely your experience matches the role
• Motivation – whether you’ve shown genuine interest in this opportunity
• Clarity – how easy it is to understand your value

A cover letter that helps secure interviews doesn’t repeat your CV. Instead, it directs attention to the most relevant parts of your experience and provides context that supports shortlisting decisions.

1. Make sure your CV is working first

Before refining your cover letter, ensure your CV clearly reflects the role you’re applying for. A well‑written cover letter cannot compensate for a CV that is unfocused or poorly structured.

To strengthen your CV:

• Prioritise experience that directly relates to the role
• Lead with achievements rather than responsibilities
• Tailor your CV for each application instead of using a single version
• Keep formatting clear and professional

Your cover letter should then build on these strengths, not repeat them.

2. Align your cover letter with your online profile

Many employers will review your LinkedIn profile either before or after reading your application. Inconsistencies between your CV, cover letter and online presence can raise questions.

To create a consistent impression:

• Ensure your LinkedIn profile reflects the same role focus as your application
• Highlight recent achievements and outcomes
• Use similar language when describing your experience

A clear and consistent story across all touchpoints helps build credibility.

3. Write a cover letter that supports shortlisting 

Your cover letter should complement your CV by answering one key question: 
Why should this employer invite you to an interview?
 

Tailor your message to the role

Use the job description to identify the most important skills or outcomes, and address them directly with evidence.

Example:
If project delivery is a key requirement, show how you’ve delivered results:
“I led a cross‑functional team to deliver a system upgrade three weeks ahead of schedule, improving reporting accuracy across the business.”

Use a clear subject line

Where applicable, include the job title and any reference number provided in the advertisement.

Example:
Application for Finance Analyst role – Ref FA1024

Keep it concise and focused

A cover letter should usually be no longer than one page. Focus on experience that supports this role, rather than your full career history.

Example:
“With four years’ experience in customer service operations, I’ve consistently improved response times and customer satisfaction scores.”

Complement your CV, don’t repeat it

Your CV outlines what you’ve done. Your cover letter explains why it matters.

Example:
“While my CV details my technical background, I’d like to highlight my experience working with non‑technical stakeholders to turn data into practical recommendations.”

Be clear about next steps

Close your letter confidently and professionally.

Example:
“I would welcome the opportunity to discuss how my experience could support your team and am available for interview at your convenience.”

Proofread carefully

Simple errors can undermine an otherwise strong application. Always:

• Check your spelling and grammar
• Read your letter aloud to test clarity 
• Ask someone you trust to review it before submitting

Common cover letter mistakes to avoid

Even strong candidates can be overlooked if their cover letter contains avoidable issues. Common mistakes include:

• Using a generic, untailored letter
• Repeating CV content word‑for‑word
• Failing to address the letter to a named contact
• Writing in a vague or unfocused way
• Ignoring key requirements in the job description
• Using an overly formal or overly casual tone
• Submitting without a clear closing statement
