How to write a strong job application

The best application explains why your actual background makes sense for this specific role. It should not feel like a generic letter sent everywhere.

Start with the job advertisement

Identify the responsibilities, skills and priorities the employer repeats or emphasizes.

Connect your background to the role

Choose two or three parts of your experience that are genuinely relevant and explain the connection clearly.

Use a natural opening

State the role you are applying for and why it interests you. Avoid overly formal clichés when a simple sentence is stronger.

Show evidence, not adjectives

Instead of saying you are 'excellent' or 'hard-working', describe responsibilities, situations or results that demonstrate the quality.

Close with confidence

Keep the ending brief. Reaffirm your interest and make it easy for the employer to continue the conversation.

Frequently asked questions

How long should a job application be?

Usually a focused application of roughly 250–500 words is enough, depending on the role and country.

Should I write a new application for every job?

At minimum, tailor the application to the specific role and employer. Generic applications are usually less persuasive.

Can AI write my application?

AI can draft and improve it, but the application should stay grounded in your real experience and should be reviewed before sending.
