ATS: what you need to know

What is an ATS?

An applicant tracking system (ATS) is software employers use to manage recruitment. It collects applications from job boards and careers sites, stores every CV in a searchable database, and moves candidates through stages such as screening, interview and offer.

For a recruiter handling hundreds of applications for one role, an ATS is a filing cabinet, search engine and to-do list in one. For you, it means your CV is usually read by software before it is read by a person. Common systems include Workday, Greenhouse, Lever, SAP SuccessFactors, iCIMS, Taleo and Teamtailor, and plenty of smaller UK-built tools.

How does an ATS work?

Most systems follow the same four steps once you click Apply:

1. Parsing. Your file is converted into plain text. Layouts that rely on tables, columns, text boxes or images can come out jumbled or missing.
2. Extraction. The software pulls out structured information: your name and contact details, job titles, employers, dates, education, qualifications and skills.
3. Matching. That information is compared with the job, including the job title, the required and desirable skills, and any screening questions you answered (such as right to work or a driving licence).
4. Ranking and searching. Recruiters sort, filter and search candidates. Many will search for a skill like "SQL" or "CSCS card" and only read the CVs that come up.

Some employers add knock-out questions ("Do you have the right to work in the UK?") that automatically screen people out. Others add online tests, video interviews or AI-assisted scoring. The decision to invite you to interview is, in almost every case, still made by a person.

Which employers use an ATS?

Nearly all large employers, graduate schemes, apprenticeship programmes and recruitment agencies use one. In the UK that includes the NHS, the Civil Service, banks, retailers and most firms with a dedicated careers site. Many small businesses use simpler tools or just email, but the advice in this guide works for those too: a clear, relevant CV is easier for anyone to read.

A quick clue: if you apply through a careers page that asks you to create an account, upload a CV and then re-type your work history, you're using an ATS.

Common ATS myths

"75% of CVs are rejected by robots"

This statistic is everywhere, and there's no solid source behind it. Most systems don't automatically reject people for being a weak keyword match. They rank and filter, and recruiters choose who to read. But if your CV doesn't mention the skills a recruiter searches for, you simply won't be found, which has the same result.

"You need a special ATS template"

You don't. A clean, single-column CV created in Word or Google Docs is exactly what parsers handle best. Fancy "ATS-optimised" designs are often worse.

"Stuffing keywords will get you through"

Repeating keywords or hiding them in white text might raise a score, but a recruiter reads the CV next. Keywords need to be in sentences that prove you've done the thing.

How to get your CV past an ATS

1. Mirror the language of the advert

Read the job advert and highlight the skills, tools, qualifications and duties it mentions. Use the same words in your CV where they're true for you. If the advert says "stakeholder management", write "stakeholder management", not "working with partners". If it says "Microsoft Excel", include both "Microsoft Excel" and "Excel".

2. Match the job title where it's honest

Job titles carry a lot of weight. If your title was "Crew Member" but you did the work of a "Team Leader", you can write "Crew Member (Team Leader duties)". Never claim a title you didn't hold.

3. Write out abbreviations once

Recruiters search in different ways. Write "Search Engine Optimisation (SEO)" or "Applied Behaviour Analysis (ABA)" the first time so both versions match.

4. Put skills in context

A skills list helps searching, but bullet points that show results win interviews. "Built a weekly sales report in Excel used by 12 store managers" contains the keyword and the proof.

5. Tailor every application

One generic CV sent to 50 roles performs worse than ten tailored ones. Keep a master CV with everything in it, then make a focused copy for each application. AutoCV keeps track of which version you sent where, and which one gets more replies.

ATS-friendly CV formatting

File name

Recruiters see your file name. Use something like Firstname-Lastname-CV.pdf, not cv final v3 (2).pdf.

Length

Two pages is standard in the UK. One page is perfect for school leavers, apprenticeship applicants and most students.

Cover letters and application forms

Cover letters and form answers are often stored in the ATS and searched in the same way. The same rules apply: plain formatting, the advert's language, and specific examples.

• Answer the question asked. If a form asks why you want to work for them, name something specific about the organisation.
• Use STAR. Situation, Task, Action, Result, with most of your words on the Action and Result.
• Don't paste your CV. Use the letter to connect your experience to this role.
• Write in a document first. Portals can time out. Draft, spell-check, then paste.

After the ATS: the human read

Recruiters often spend under a minute on a first read. Make that minute count: a three-line profile tailored to the role, your most relevant experience near the top, numbers wherever you have them, and no spelling mistakes. Getting past the software only matters if the person reading is convinced too.

Then keep track. Note the date you applied, the CV version you used, and any contact names. If you hear nothing after one to two weeks, a short follow-up is appropriate. Patterns across your applications (lots of views, few replies) tell you what to fix next. That's exactly what the AutoCV tracker is for.
