| ATS capability | Practical effect | Planning use |
|---|---|---|
| Resume parsing | Extracts key aspects of each resume into structured fields for like-for-like comparison | Test it on real resumes from your own roles before you commit to a vendor. |
| Keyword filtering | Some systems let recruiters filter candidates by keywords and pull reports of people with relevant experience | Use it to narrow a pool, not to make the final call. |
| Funnel reporting | A Candidate Funnel report identifies bottlenecks in the hiring pipeline | Look at where roles stall; this is where time to hire is decided. |
| Job board integration | Connects with boards such as Indeed, ZipRecruiter and LinkedIn | Confirm the boards you actually post to are supported. |
| Automated candidate emails | Keeps candidates informed at each phase of hiring | Write stage messages early so candidate experience stays consistent. |
| HRIS transfer | A hired candidate’s data moves automatically to employee records | Check field mapping against the HR system you already run. |
Capabilities per HiBob’s applicant tracking glossary and BambooHR’s ATS product page; the vendor features vary by product.
An ATS applicant tracking system manages recruiting from posting a job to tracking applications, so its value depends on whether its parsing, filters and reports match how your team really hires.
This guide covers the employer side first and then shows how applications are screened. For the wider process around the software, see our guide on how to hire employees.
Effects on time to hire, cost per hire and candidate experience
An ATS changes hiring mainly by making each stage visible and measurable. HR Cloud names time-to-hire and cost-per-hire as example KPIs that these tools measure. Measuring them is the supported benefit; a faster or cheaper process follows only if the team acts on what the reports show. Your own figures from before the rollout are the most useful benchmark, because they reflect your roles, boards and approval chains.
Time to hire
Time to hire is the span from opening a role to a hire, and an ATS affects it by exposing where candidates wait. Reporting such as BambooHR’s Candidate Funnel report is built to identify bottlenecks. Because the system moves candidates through predefined pipeline stages, as Asymbl describes, each delay has a stage attached to it.
- Find the slowest stage first. Fixing one stalled step usually teaches more than tuning every step at once.
- Record the starting position. Capture time to hire and cost per hire before go-live so later changes can be judged fairly.
- Keep the stages meaningful. Stages nobody uses blur the reports and hide the real delay.
Cost per hire
Cost per hire is tracked alongside time to hire in the same reporting, so the two can be read together. Treat the number as an outcome of the whole process, including job board choices and the time recruiters spend on administration, rather than a feature of the software itself.
Candidate experience
Candidate experience improves when applicants hear from you at every phase. BambooHR describes automated, personalised emails for this purpose. The trade-off is that automation sends whatever you configure, so poorly worded templates reach every applicant. Review the wording at each stage before launch, and make sure a person can still answer questions that automated messages do not.
Screening from the applicant’s side
Job seekers get past an ATS by being parsed correctly and by using the words the employer filters on. The system extracts key aspects of each resume into structured fields, as HiBob explains, so that applicants can be compared like for like.
Keyword filtering then narrows the field. Asymbl notes that this narrows efficiently but does not assess quality, and observes that candidates who have learned to write for ATS filters advance. HR Cloud adds the risk: a system can screen out strong candidates who use different words on their resumes.
- Mirror the posting’s wording where it is true. If the advert names a skill or tool you have used under a different label, use the advert’s term.
- State experience plainly. Clear, specific statements give parsing more to extract into fields.
- Do not rely on keywords alone. Filters narrow the pool, and a person still weighs quality, so concrete results on the page still count.
Employers should read this the other way round. Recruiters should use keyword filters to narrow the pool, and a candidate who describes the same skill in different words may need a second look.
How an ATS works behind the screen
An ATS accepts applications, parses resumes into structured fields, moves candidates through pipeline stages and stores compliance records, according to Asymbl. HiBob lists the wider set of functions: sourcing, screening, tracking, interview scheduling, automated emails, new-hire paperwork, a central candidate database and reporting.
Job board integration
Job board integration is how postings go out and applications come in. BambooHR states that its ATS integrates with boards such as Indeed, ZipRecruiter and LinkedIn, and that it offers integrations for connecting other tools. Those details describe one vendor, so use them as a prompt to check coverage rather than a standard.
HRIS hand-off
Once a person is hired, their data moves automatically to the core HR platform, as HR Cloud describes. An HRIS (human resource information system) holds employee records, so this hand-off saves re-keying details and is worth confirming in a demo.
Choosing an ATS
Choose the system that fits your hiring routine and connects to the tools you already use. Beyond Intranet says it should be quick and easy to set up without disrupting operations, which is a sensible first filter.
- Parsing quality. Run real resumes through the demo and compare the extracted fields with the originals.
- Job board coverage. List the boards you use and check each one against the vendor’s integration list.
- HRIS connection. Confirm that data for hired candidates reaches your employee records, and ask what fields transfer.
- Reporting. Check that time to hire, cost per hire and stage bottlenecks can be reported without exports.
- Offer handling. Some products include offer letter templates that auto-populate candidate details for different positions. If you draft offers outside the system, our guide to 7 Job Offer Letter Templates You Can Customize Today (Quick, Professional & Legal‑Ready 2026) – Gozaik helps you standardise them.
Small teams with a simple process may value ease of setup above depth of features. Larger teams with several boards and a separate HR platform should weight integrations and reporting more heavily.
Implementation checklist
Implementation works best as a sequence of small, checkable tasks, since the aim is to avoid disrupting day-to-day hiring. Ask the vendor for its setup timeline in writing, because the supplied evidence gives no standard duration.
- Map your current process. Write down the steps a candidate goes through today and match them to the system’s pipeline stages.
- Migrate existing data. Move candidate records from old systems, and check a sample of records after the import.
- Connect job boards and the HRIS. Test that an application from each board arrives and that a hire reaches employee records.
- Set up stage communications. Configure the automated emails that candidates will see.
- Test with live material. Use a real posting and sample resumes to check parsing and filters before inviting hiring managers.
- Review the first reports. Compare time to hire and cost per hire with your pre-launch baseline.
Once candidates reach the final stages, pair the pipeline with a consistent step such as Reference Check Questions: The Essential Guide And Sample Questions To Hire With Confidence In 2026 – Gozaik, so the last decisions are documented as carefully as the early ones.
Data privacy and compliance
An ATS supports compliance mainly through its record of what happened to each candidate. HR Cloud explains that the system automatically tracks every candidate action and decision, and that this record is needed to show you follow Equal Employment Opportunity (EEO) laws and other rules.
Applicant data is personal data, so HiBob stresses that employers must meet GDPR best practice standards. Which rules apply depends on where you hire and where applicants live, so confirm the requirements with your legal adviser before configuring retention and access.
Frequently asked questions
Can candidates choose their own interview time?
Yes, in systems that offer self-service scheduling. Candidates pick from times and dates the employer has set, as BambooHR describes with its preset options.
What is a talent pool in an ATS?
It is a stored bank of candidates that recruiters can search later. HiBob notes that some systems keep talent banks alongside keyword filtering.
Can an employer keep unsuccessful applicants on file?
Some systems include consent boxes in their communications that let the employer keep details on record. Use them in line with your privacy obligations.
What costs come with implementing an ATS?
Beyond Intranet lists setup, data migration, workflow customisation, upgrades and maintenance. Ask a vendor to price each item separately so comparisons are fair.
