Cover Letter Guide

When you need one and how to write it.

Short answer: Most applications don't require cover letters, but when they do (or when you're going around normal channels), a good cover letter connects your experience to their specific needs and shows you've done your homework. Keep it to 3-4 paragraphs max.

When to use this

Do this first if:

  • The application specifically requires a cover letter
  • You're reaching out directly to a hiring manager
  • You're making a career change and need to explain your pivot

Skip this if:

  • The application doesn't have a cover letter field
  • You're applying through a referral who can vouch for you
  • You're mass-applying and a generic letter would hurt more than help

Cover Letter Checklist

Elements of an effective cover letter

1
Specific opening

Reference the role and something specific about the company that resonates with you.

2
Bridge statement

Connect your experience to their needs with 1-2 concrete examples.

3
Evidence of research

Show you've looked at their product, challenges, or recent news.

4
Clear ask

State what you want (interview, conversation) and make it easy to follow up.

5
Brevity

Keep it to 3-4 paragraphs. Hiring managers skim—respect their time.

Example

Before

I am writing to apply for the Software Engineer position at your company. I have 5 years of experience and strong skills in Python and AWS.

After

Your recent blog post on scaling recommendation systems caught my attention—I solved a similar challenge at TechCorp, reducing latency by 60% while doubling throughput. I'd love to bring that experience to your team as you expand into real-time personalization.

The 'after' version shows research, relevant experience, and specific value—all in two sentences.

Frequently asked questions

Do I always need a cover letter?

No. Only write one if it's required, you're reaching out directly, or you have something important to explain (career change, relocation).

How long should a cover letter be?

3-4 paragraphs, under 200 words. Hiring managers skim—get to the point quickly.

Should I repeat my resume in the cover letter?

No. The cover letter should add context or connect dots that the resume doesn't, not repeat it.

How do I address a career change in a cover letter?

Focus on transferable skills and genuine interest in the new field. Explain 'why' you're changing, not just 'what'.

Should I mention salary expectations?

Generally no, unless the posting specifically asks for it. Save compensation discussion for later stages.

How do I find the hiring manager's name?

Check LinkedIn, company About pages, or the job posting. If you can't find it, 'Dear Hiring Team' works.
