Your professional bio and your resume should tell the same story but in different voices. Here is how to write a bio that complements your resume without duplicating it.
Third person vs. first person
Formal speaker bios and some company website profiles use third person. LinkedIn About sections use first person. Match your voice to the context.
Lead with what you do, not where you went to school
Unless you are in academia or the credential is unusually relevant, your most recent and significant professional work should lead your bio, not your undergraduate institution. For more on this, see our guide on chatgpt vs professional resume writer.
Keep it short for most contexts
A standard professional bio is 100 to 200 words. A longer bio is appropriate for academic contexts or speaker profiles where more detail is expected.
Update it regularly
Your bio should reflect your current role and current professional focus. A bio that describes a role you left two years ago creates a disconnect for anyone who reads both your bio and your LinkedIn profile.

Frequently Asked Questions
How long does a recruiter spend looking at a resume?
Recruiters typically spend 6-10 seconds on an initial scan. They look for job title relevance, company names, and whether the most recent role is at the right level for the position.
What do recruiters look for first on a resume?
Most recruiters look first at your most recent job title and company, then check dates for gaps or progression, then assess whether the experience level matches what they need.
Should I include a summary at the top of my resume?
Yes, for experienced candidates. A 2-3 sentence summary that speaks directly to your target role helps recruiters understand your value instantly.
How many bullet points should each job have?
3-5 bullets for recent roles, 1-2 for older ones. Each bullet should describe an accomplishment or outcome, not just a task or responsibility.
Recruiters spend an average of six to ten seconds on their first pass through a resume. That initial scan focuses almost entirely on job titles, company names, and bullet points. If those three things do not immediately connect your experience to the role, your resume may not make it to a second read. Understanding this reality changes how you approach every element of your document, from the font size to the order of your sections. For more on this, see our guide on sales resume guide.
In my experience reviewing thousands of resumes, the candidates who get callbacks consistently share one trait: they write about impact rather than activity. Instead of listing what they were responsible for, they describe what changed because of their work. A simple shift from “managed social media” to “grew Instagram engagement by 47% in six months by shifting to video-first content” tells a recruiter exactly what you bring to a new role.
Formatting also plays a larger role than most candidates realize. Applicant tracking systems parse resumes before a human ever sees them. Tables, text boxes, headers, and footers often fail to parse correctly, which means critical information disappears from your digital file. Keeping your format simple, with standard sections and clean column layouts, ensures that your content survives the screening process intact.
The length question comes up constantly. For most professionals with under ten years of experience, one page is the right target. For senior leaders and executives, two pages is acceptable when every line adds genuine value. The test is not word count. It is density. If a recruiter could cut any section without losing information that differentiates you, that section should go. For more on this, see our guide on nurse resume guide.

Anonymous and approximate. We store one number for this article and nothing about you.
Email digest
We also run a layoff tracker, built from company filings and official notices. A plain email summary of what changed on these trackers: the period’s headline numbers and the largest new entries, with links back to the source pages. No images, no tracking pixels. You confirm your address by clicking a link we email you, and every email carries a one-click unsubscribe. Details in the privacy note below.
Privacy note: what we store and how to erase it
What we store: your email address, the choices above, and timestamps (signed up, confirmed, last sent). Nothing else about you. There is no open tracking and no tracking pixel, so we cannot tell whether you opened an email.
About the links: links in the digest pass through a counter on this site that adds 1 to a total for that link and sends you straight on. It records no identifier, no IP address and no browser details, so it counts how many times a link was followed and can never say who followed it.
What it is used for: sending you exactly the emails you ticked, nothing else. The address is never shared, sold, or used for any other purpose.
How to erase it: click the unsubscribe link in any email. That stops all sending immediately, and unsubscribed addresses, along with signups that were never confirmed, are hard-deleted automatically after 30 days. You can also ask via the contact page.
