How this guide will help
In the sections below, you’ll see exactly how each mistake shows up on a resume and what to do instead.
This will help you make practical improvements as you write, edit, or tailor your resume for each application.
Do resume mistakes depend on your situation?
Some resume mistakes depend on your experience level, career goals, and the role you’re applying for.
For example, entry-level candidates may benefit from a brief summary, while experienced professionals should focus on results and specialization.
The key is to think about relevance.
Every section, detail, and decision on your resume should support your fit for the specific role, rather than following generic advice without context.

This means tailoring your content to the job, showing measurable results, using a clean format, and carefully checking for errors before you submit.
Most mistakes happen during drafting, tailoring, or final review, so it’s important to check each stage carefully.

What are the most common resume mistakes?
These are the most common resume mistakes that can prevent your resume from being shortlisted of getting an interview, even if you have the right experience.
Understanding how they show up and how to fix them will help you create a clearer, more effective resume.
1. Using a resume objective when it’s not needed
A resume objective is often unnecessary for experienced candidates and can waste valuable space at the top of your resume.
Employers already know the role you are applying for, so repeating it adds little value.
Replace it with a professional summary that highlights your experience, skills, and what you can offer.
- Example: "Objective: Seeking a marketing role" → "Marketing manager with 6+ years of experience driving 20%+ campaign growth"
2. Including irrelevant experience or details
Adding unrelated experience or information can distract from your most relevant qualifications.
Hiring managers are scanning for fit, so anything that does not support the role may weaken your application.
Focus on recent, relatable experience that clearly aligns with the job.
- Example: "Retail job from 10 years ago" (no relevance) → "Customer-facing experience highlighting sales and communication skills"
3. Providing too little detail for key roles
If your most relevant roles lack detail, employers cannot fully understand your impact.
Short or vague descriptions can make strong experience look underwhelming.
Add clear bullet points that explain what you did and the results you achieved.
- Example: "Worked on client projects" → "Delivered 12 client projects on time, improving retention by 15%"
4. Adding a references section
Including references on your resume is outdated and takes up space that could be used more effectively.
Employers typically ask for references later in the hiring process.
Keep a separate document ready instead and only share it when requested.
- Example: "References available upon request section" → (Removed to create space for achievements)
5. Making mistakes in your skills section
Listing too many generic or obvious skills can reduce the impact of your resume.
Recruiters are looking for specific, job-specific abilities rather than broad or overused terms.
Highlight technical and role-specific skills that support your experience.
- Example: "Team player, hardworking, communication" → "SQL, Tableau, financial forecasting"
6. Not tailoring your resume
Sending the same resume for every application makes it harder to stand out.
Employers want to see how your experience fits their specific needs, not a general overview of your background.
Tailor your resume by aligning your skills and achievements with the job description.
- Example: Generic resume for all roles → Resume updated with keywords and achievements relevant to the job posting
7. Including salary expectations
Adding salary requirements to your resume can limit your opportunities before a conversation even begins.
Employers may use this information to filter candidates too early.
Keep salary discussions for later stages of the hiring process.
- Example: "Salary expectation: $70,000" → (Discussed later in interview instead)
8. Listing responsibilities instead of achievements
Describing what you were responsible for does not show how well you performed.
Employers want to see the results of your work and the value you brought to previous roles.
Centre around achievements and include measurable outcomes where possible.
- Example: "Managed a team" → "Led a team of 8, increasing productivity by 25%"
9. Using the wrong resume length
A resume that is too long can overwhelm recruiters, while one that is too short may leave out important details.
Most candidates should aim for one to two pages depending on their experience level.
Include enough information to demonstrate value without adding unnecessary content.
- Example: 3+ pages of early career roles → Condensed to 2 pages focusing on recent, relevant experience
10. Submitting resumes with grammar or spelling errors
Typos and grammar mistakes can quickly create a negative impression.
Even small errors suggest a lack of attention to detail.
Always proofread your resume carefully before submitting it.
- Example: “Manger” instead of “Manager” → Corrected spelling after proofreading
11. Including a photo
Adding a photo is usually unnecessary and may even create bias in the hiring process.
Many employers prefer resumes without personal details that are not job-related.
Keep the focus on your skills and experience.
- Example: Resume with headshot → Clean resume focused on experience only
12. Listing hobbies that are not relevant
Hobbies rarely add value unless they directly relate to the role or demonstrate a useful skill.
Including them can take up space better used for professional experience.
Only include hobbies if they strengthen your application.
- Example: "Hobbies: watching TV, traveling" → (Removed or replaced with relevant volunteer experience)
How do I check my resume before submitting?
Before submitting your resume, review it for relevance, clarity, and accuracy to make sure it reflects the job you’re applying for.
A final check should confirm that your content is tailored, your achievements are clear, and there are no errors that could distract a recruiter.
Step-by-step resume check
- Match your resume to the job description: Make sure your skills, experience, and keywords reflect what the employer is asking for. If a recruiter scans your resume quickly, the match should be obvious.
- Check for measurable results: Review each bullet point and ask whether it shows a clear outcome or impact. Add numbers, percentages, or results where possible.
- Scan for formatting consistency: Look at spacing, bullet points, dates, and headings to ensure everything is aligned and easy to read. A clean layout helps recruiters find key information quickly.
- Proofread carefully: Read your resume slowly or backwards to catch spelling and grammar errors that tools might miss. It also helps to ask someone else to review it for a fresh perspective.
- Test readability: Skim your resume in 5-10 seconds and check whether your most relevant experience stands out. If key information is hard to find, adjust your layout or wording.
Key takeaways
- Tailor your resume for every job by aligning your experience and skills with the job description
- Focus on achievements and results, not just responsibilities
- Keep your resume clear, relevant, and easy to scan with consistent formatting
- Proofread carefully and get a second opinion before submitting
