Typos and inconsistent formatting
A typo in the header of your resume tells a hiring manager about your attention to detail before they read a word. Proofread multiple times, use Grammarly, and have a trusted person review your final version.
Generic summaries that say nothing
If your summary reads “seeking a challenging role in a dynamic environment,” you have written a summary that applies to no one. Replace it with specific experience, specific outcomes, and what you are specifically looking for. For more on this, see our guide on nurse resume guide.
Burying your best achievements
Do not bury your most impressive bullet at the bottom of a role section. Lead with your strongest result. Recruiters read top to bottom and lose attention quickly.
Irrelevant or outdated information
Remove jobs from before 2005 unless they are directly relevant. Remove outdated technologies. Remove skills you cannot demonstrate. Clean resumes signal good judgment.

Frequently Asked Questions
What is the STAR method?
STAR stands for Situation, Task, Action, Result. It is a framework for answering behavioral interview questions by providing context, your role, what you did, and the outcome.
How long should a STAR answer be?
Two to three minutes. Situation and Task together should take 30-45 seconds. Spend the most time on the Actions and always end with a concrete Result.
What are common behavioral interview questions?
Common ones include: “Tell me about a time you handled conflict,” “Describe managing competing priorities,” and “Give an example of when you failed and what you learned.”
Should I memorize STAR answers word-for-word?
No. Memorized answers sound robotic. Know your 6-8 strongest stories well enough to tell them naturally. Practice key points, not exact wording.
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 chatgpt vs professional resume writer.
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 write an executive resume that gets interviews.
