For UK graduates entering the job market, understanding how Applicant Tracking Systems (ATS) work is no longer optional — it is essential. Research suggests that up to 75% of CVs are rejected before a human recruiter ever reads them, and the primary gatekeeper is the ATS.

This guide explains what ATS software looks for, the most common mistakes graduates make, and how to ensure your CV gets through to a real person.

What Is an Applicant Tracking System?

An ATS is software used by employers to manage the volume of applications they receive. It scans each CV, extracts key information (education, work experience, skills), and scores the document against the job description. Candidates whose scores fall below a certain threshold are automatically rejected.

Most major UK graduate recruiters use ATS filtering as a first-stage sift. This includes firms such as PwC, Deloitte, KPMG, Aldi, the Civil Service Fast Stream, Lloyds Banking Group, and BAE Systems. If you are applying to any of these organisations, your CV will be processed by an ATS before it reaches a recruiter.

Common CV Mistakes That Lead to Rejection

1. Complex Formatting

A visually elaborate CV may look impressive, but ATS software struggles with columns, text boxes, tables, and graphics. These elements can cause the parser to misread or skip content entirely.

Recommendation: Use a single-column layout with a standard font (Arial or Calibri, 10–11pt). Save your CV as a .docx file unless the employer specifically requests PDF. Avoid templates from design-heavy platforms that use non-standard formatting.

2. Generic Content Across All Applications

Sending the same CV to every employer is the most common mistake graduates make. Each job description contains specific keywords and required competencies. The ATS is programmed to look for these exact terms.

Recommendation: Tailor your CV for each application by incorporating the specific language used in the job description. If the employer asks for "stakeholder management", use that exact phrase rather than "working with people". Our AI CV Checker can identify which keywords your CV is missing in seconds.

3. Incorrect File Format

While PDFs are excellent for preserving formatting, some ATS platforms parse them inconsistently. This is particularly true for PDFs created with compression or non-standard fonts.

Recommendation: Submit your CV as a .docx file unless the application instructions specify otherwise. Before submitting, run your CV through the CV Checker to confirm it parses correctly.

4. Weak Personal Statements

Opening statements such as "I am a highly motivated graduate seeking a challenging role" add no value. They do not differentiate you from other applicants and are largely ignored by ATS software.

Recommendation: Replace the generic statement with a concise two-to-three-line professional summary that includes your degree discipline, a key achievement, and your career objective. Tailor this summary to the specific role to improve your ATS match rate.

5. Buried Skills Section

Placing your skills section at the bottom of the document, or embedding technical competencies within descriptive paragraphs, reduces the likelihood that the ATS will capture them.

Recommendation: Include a dedicated skills section positioned immediately after your education summary. Use clear, scannable formatting and list technical competencies explicitly (e.g., Python, SQL, Excel, Mandarin).

How to Optimise Your CV Before Submitting

Follow this checklist before sending your next application:

  • Format: Use .docx, single-column layout, standard typeface
  • Keywords: Mirror the language used in the job description
  • Structure: Education → Skills → Work Experience → Projects
  • Conciseness: Aim for two pages maximum. Remove anything that does not directly support your application
  • Verification: Use the AI CV Checker to preview exactly what the ATS will see before you click submit

The final step is particularly valuable because it removes guesswork. You receive instant, structured feedback on how your CV performs against ATS criteria, allowing you to make targeted improvements before submission.

Making your CV ATS-compatible is not about deceiving the system. It is about presenting your qualifications in a format that the system can process accurately, so that a human recruiter has the opportunity to evaluate your potential.
