How ATS and AI Screen CVs: A Brighton Applicant Guide

If you apply for a part-time job through an online form, your CV may pass through recruitment software before a hiring manager opens it. That does not mean every CV is judged by one mysterious robot, or that a missing keyword always causes rejection. Applicant tracking systems (ATS), fixed screening rules and artificial intelligence (AI) are different tools, and employers configure them differently.

This guide explains what each tool can do, what official sources actually confirm, and how to prepare a clear CV without resorting to keyword stuffing or unreliable online tricks. It is written for Brighton applicants, including people applying for retail, hospitality, student and entry-level roles. If applications are disappearing without a response, also use our 10 practical fixes for job applications that get no reply.

The Short Answer: What Can Happen to Your CV?

A recruitment system may do one or more of the following:

1. Store and organise your application. An ATS can hold your CV, answers, contact details and progress through the hiring stages.
2. Parse your CV. A parser extracts information such as your name, work history, education and skills into database fields.
3. Apply fixed rules. An employer may use yes-or-no questions about matters such as right to work, a required qualification or availability.
4. Search or filter applications. Recruiters may search for employer-defined words, qualifications, locations or skills.
5. Score or rank applicants. Some systems use algorithms or AI to compare application information with the job requirements.
6. Support or make a decision. A recruiter may review the output, or a system may progress or reject an application without meaningful human involvement.

The UK government's responsible AI in recruitment guidance confirms that qualifying screening tools can use natural language processing, keyword searches and employer-defined criteria to score CVs or written applications. It also describes CV matching tools that extract information and may compare it semantically with a predetermined profile. These are possible functions, not proof that every employer uses them.

ATS, Automation and AI Are Not the Same Thing

The terms are often mixed together online, which creates bad advice. A useful way to separate them is to ask what the system is actually doing.

Applicant tracking system

An ATS is the platform used to collect and manage applications. It may include parsing, search, filters, scheduling and reporting. It can also connect to separate AI features. Merely applying through an ATS does not prove that AI scored your CV.

Rule-based screening

A fixed rule follows an instruction chosen in advance. For example, an application form may ask whether you hold a qualification that the advert identifies as essential. A particular answer may stop the application.

The Information Commissioner's Office (ICO) found employers using these binary questions for requirements such as right to work and mandatory qualifications. Its 2026 recruitment findings distinguish a static rule from automated decision-making under data protection law: if a human has already defined the outcome for each answer, the rule itself is not making a new judgement about you. It can still affect your application immediately.

AI or algorithmic matching

A matching tool may infer skills from an application, compare them with a job requisition, and produce a rating or ranking. Official product documentation shows why there is no universal ATS score. Workday's Candidate Skills Match uses machine learning to compare skills derived from an application and job requisition, with results such as Strong, Good, Fair or Low. Oracle Recruiting documents a separate generative-AI feature that can evaluate parsed education, experience and skills to generate ratings. Different products assess different information, and employers decide which features to enable and how to use the output.

A Realistic Application Journey

There is no single sequence used by every Brighton employer, but official guidance supports this conditional model.

1. Your file and form answers enter the system

The employer receives the CV plus anything you type into the application form. Treat the form as important evidence, not as a duplicate you can rush through. The National Careers Service application-form guidance recommends completing relevant work history, matching truthful wording to the advert, proofreading answers and keeping a copy.

2. A parser may extract CV data

The system may try to identify contact details, employers, job titles, dates, education and skills. Parsing is data extraction. It is not automatically a judgement about whether you deserve an interview.

Parsing accuracy varies. Greenhouse lists graphics, image-only files, tables, columns, headers, footers and text boxes among the causes of an unsuccessful or partial resume parse. Workable, by contrast, says its parser can scan image-based CVs as well as documents. This difference is important: advice that claims every ATS reads the same layout is not credible.

3. Fixed questions may be checked

A form may ask about legal or essential conditions. Read the wording closely and answer honestly. If a question is unclear, contact the employer instead of guessing. An immediate rejection can result from a fixed answer, a closed vacancy, a duplicate application or another workflow rule. Speed alone does not prove that AI analysed your CV.

4. Search, filters or matching may narrow the pool

Recruiters may search for a skill or qualification. An algorithm may also compare the application with the role and produce a score or ordering. According to the ICO's Recruitment Rewired findings, these tools are particularly relevant to high-volume and early-career recruitment, but they are not used universally and their role varies by employer and vacancy.

5. A person may review the application

A recruiter can use a score as decision support and still examine your evidence. In other workflows, lower-ranked applicants may never receive a genuine human review. The ICO says meaningful human involvement requires a person with the competence and authority to influence or change the result; a token check or automatic approval is not enough.

The Safest CV Format for Online Applications

No format can guarantee an interview or perfect parsing. The aim is to make your information easy for both software and people to identify across different systems.

Follow the portal's instructions first

Use an accepted file type and stay within the stated size limit. Do not rename an unsupported format with a .pdf or .docx extension. If the employer asks you to type information into fields as well as upload a CV, complete both. Parsed fields can be wrong, so check and correct them before submitting whenever the portal allows it.

Keep a simple, text-based version

For general online applications, a one-column CV with selectable text is a sensible cross-system precaution. Use familiar section headings such as:

• Contact details
• Profile
• Key skills
• Work experience
• Education
• Volunteering or projects

Place your name, phone number and email address in the main document body rather than only in a header, footer or floating text box. Avoid using an image to display essential information. A designed CV can still be useful for a creative portfolio, but keep a plain version for portals where you do not know the parser.

The National Careers Service CV guide independently recommends a clear font, consistent styling, headings, bullet points, concise writing and a CV tailored to the role. It also advises including your name, phone number and email address, while leaving out age, date of birth, marital status and nationality.

Choose PDF or DOCX based on the application

There is no honest universal answer to the PDF-versus-DOCX question. Workday documents support for DOC, DOCX, PDF, RTF, TXT, HTML and HTM in its skills-matching process. Workable accepts PDF, DOC, DOCX, RTF, HTML and ODT for CV uploads. Other portals may impose different rules.

Use the format requested by the employer. If both PDF and DOCX are accepted, use a text-based file that opens correctly, keeps the intended order, and contains no password protection. A scanned PDF is not equivalent to a text PDF.

Use dates and titles consistently

Give each experience a recognisable structure: job or activity title, organisation, location if useful, and dates. Then add short bullets showing what you did and the result. For a first CV, evidence can come from school or college projects, volunteering, clubs, caring responsibilities or community activities. Our CV guide for applicants with no experience includes a practical structure.

How to Use Keywords Without Stuffing Your CV

Keywords are not magic passwords. They are useful because they help a recruiter or system connect your real evidence to the employer's requirements.

Build a requirement list

Read the advert and separate the requirements into:

• essential qualifications or legal conditions
• role-specific skills
• tasks and responsibilities
• availability or location requirements
• personal qualities that need evidence

Then mark which ones you genuinely meet. Use the employer's normal terminology where it accurately describes your experience. For example, if the advert asks for customer service and you helped visitors at a college event, use the phrase "customer service" and explain what you did.

Put evidence next to the term

A bare list of words is weaker than a short example. Compare:

• Weak: Customer service, teamwork, communication.
• Stronger: Welcomed visitors at two college open evenings, answered course questions and directed families to the correct rooms.

The second version gives a human reviewer context and still contains relevant concepts that a search or matching tool may identify. Where a recognised abbreviation matters, you can include both forms naturally, such as "point of sale (POS)", but only if you have that experience.

Do not hide or repeat keywords dishonestly

Avoid white text, blocks of repeated terms or skills you cannot demonstrate. Official sources do not support the claim that these tricks reliably improve selection. They can make the application inaccurate and poor for a person to read. Tailoring means selecting truthful, relevant evidence, not copying the entire job advert.

A Five-Minute CV Parsing Check

This check cannot reproduce an employer's ATS, but it can expose obvious file problems before you apply.

1. Open the final file on a second device or in another viewer.
2. Select and copy all the text into a plain-text editor.
3. Check whether your name, phone number, email, headings, employers, dates and bullets appear in a logical order.
4. Check that important information is not represented only by an icon, image or chart.
5. Confirm the filename is professional, for example Pedram-Surname-CV.pdf.
6. Upload the file and inspect every field the portal fills automatically. Correct any parsing mistakes before submission.
7. Save a copy of the advert, your CV and your form answers.

Passing this check does not prove that an algorithm will rank the CV highly. It only confirms that the document's basic text survives a simple extraction test.

Can AI Reject a CV Before a Human Reads It?

Yes, a system can reject or deprioritise an application without a human genuinely reviewing it, but you should not assume this happens in every process. The ICO's jobseeker guidance on automated recruitment decisions explains that an algorithm may analyse words, skills or qualifications, then score, rank or filter an application. A score below a set threshold may lead to rejection before human review.

The ICO also found that some employers thought a person was meaningfully involved when the evidence suggested otherwise. That finding came from voluntary engagement with more than 30 employers between March 2025 and January 2026. It is evidence of a real compliance concern, not a statistic describing all UK employers.

Your UK Rights When Recruitment Is Automated

Automated recruitment is not automatically unlawful. Current ICO guidance says employers can use automated decision-making when they have a valid reason, but safeguards apply when a significant decision is made without a real person involved.

In that situation, you have the right to:

• be told that automated decision-making is being used and how it may affect the process
• receive a fair outcome
• contest the decision and explain your point of view
• request human intervention or review

Start with the employer's job advert, applicant privacy notice and recruitment privacy policy. Look for terms such as automated decision-making, profiling, matching, ranking, scoring, artificial intelligence or machine learning. A generic statement that the organisation uses technology may not explain whether a particular vacancy uses it.

If you receive an unexpected rejection and have a specific reason to suspect a solely automated decision, you could write:

Please confirm whether a solely automated decision was used in relation to my application. If it was, please provide information about how the decision affected my application and arrange for a person with authority to review it. I would also like the opportunity to explain my relevant experience.

Keep the request factual. An employer may confirm that the decision involved meaningful human judgement or that a fixed eligibility rule applied instead. If your data protection concern is not resolved, the ICO explains how to raise a concern about an organisation.

Disability, Accessibility and Reasonable Adjustments

Technology must not remove an applicant's right to a fair recruitment process. Acas guidance on recruitment discrimination says employers must make reasonable adjustments for disabled applicants or interviewees, and that this can apply at any stage of recruitment. An adjustment could include a different application format or changes to an online test.

The government's responsible-AI guidance adds that an employer should plan alternatives when technology puts an applicant at a substantial disadvantage. If the disadvantage cannot be removed within the tool, the employer may need to use a different recruitment format.

Use the adjustment contact in the advert or careers site and describe the barrier and the change you need. You do not need to diagnose the employer's software. For example:

I am requesting a reasonable adjustment to the online screening stage because the current format places me at a substantial disadvantage. Please let me know whether the information can be provided in an accessible format or assessed through an alternative process.

For advice about discrimination or adjustments, contact the Acas helpline. For a data-protection issue involving your application information or an automated decision, use the ICO route.

ATS and AI CV Myths

"Every company uses an ATS to reject CVs"

Not established. Employers use different processes, and an ATS can simply manage applications. Even when an ATS is present, AI scoring may not be enabled.

"Missing one keyword means automatic rejection"

Not as a universal rule. Some employers use exact searches or fixed criteria; some systems use semantic skills matching; others rely on manual review. Essential screening questions can matter more than the wording in the CV.

"There is one ATS score I can optimise"

False. Official Workday and Oracle documentation describes different features, inputs and rating methods. The employer's configuration also matters. A score from an online CV checker is not access to the employer's actual setup.

"An instant rejection proves AI rejected me"

No. It may reflect a fixed question, vacancy status, duplicate rule or another automated workflow. Ask for clarification if there is a concrete reason to believe a significant decision was solely automated.

"A decorative CV can never be parsed"

Too absolute. Parsing capability differs between products. However, official Greenhouse support documents several complex layouts that can cause partial or failed extraction. A simple, text-based version reduces avoidable uncertainty.

"AI can replace truthful evidence"

No. Whether you use a writing assistant or not, you remain responsible for the accuracy of your application. Check every claim, remove generic wording and make sure you can discuss each example at interview.

Final Checklist Before You Apply

• Read the advert and identify genuine essential and desirable criteria.
• Use the file type and size requested by the employer.
• Keep essential text in a clear, one-column structure.
• Put your contact details in the document body.
• Use standard headings, consistent dates and complete job or activity titles.
• Reflect relevant advert wording only where it truthfully describes your evidence.
• Complete every application field and check any automatically extracted details.
• Test that the CV's text copies in a sensible order.
• Save the advert, submitted CV and form answers.
• Check the privacy notice for automated decision-making information.
• Request a reasonable adjustment if a screening method creates a disability-related disadvantage.

A clear CV cannot guarantee an interview, and there is no evidence-based trick that defeats every recruitment system. The practical goal is simpler: make accurate evidence easy to extract, easy to match with the vacancy and easy for a person to verify.
