Learn what a cover letter is, what it should add beyond a resume, when employers expect one, and how a strong letter connects selected evidence with a specific job.
Quick answer
A cover letter is a short application document that explains why your background is relevant to a specific role and why the opportunity matters to you. Unlike a resume, it uses a narrative to connect selected evidence with the employer's needs. It should not repeat the resume line by line.
What matters most
The letter interprets selected resume evidence in the context of one employer and role.
It can explain a credible reason for the application that a structured resume cannot express efficiently.
Career changes, gaps, relocation, return-to-work situations, or unusual paths may benefit from brief explanation when relevant.

Open the resume engineGuide 01
The resume is optimized for scanning structured evidence. The cover letter gives you a small amount of narrative space to connect that evidence, explain a transition, and show why the role is a deliberate choice. Good letters make the application easier to interpret rather than longer.
If the employer explicitly says no cover letter, follow the instruction. If it is optional, consider whether you have useful context worth adding.
Guide 02
Open with the target role and a credible connection. Use the body for one or two examples that demonstrate relevant capability, then connect those examples to the employer's needs. Close professionally and concisely.
Avoid generic company praise, copied mission statements, or a paragraph-by-paragraph restatement of the resume.
Guide 03
Dates, titles, employers, technologies, metrics, and project names should agree across documents. The letter can add interpretation but should not suddenly expand your ownership or invent context that the resume does not support.
A shared visual identity can make the application coherent, while the letter itself should remain a simple reading experience.
