TL;DR: The software reviews the candidate’s resume and sorts their experience, extracts their skills, compares them with the requirements for the job, and assists in filtering and ranking applications. Although there is much resume screening software that uses AI and NLP technology to find the right candidates, the human brain is always part of the recruiting process.
All you need to know is how the software works to understand the process through which the system gets the data from the CV and uses it to perform certain tasks, like analyzing the qualifications of the candidate in comparison with the job profile. Imagine you are a recruiter and there are 500 CVs for one single job profile. The resume screening software takes care of all these procedures automatically, leaving the recruiters free to focus on the relevant resumes. However, there is a lot more behind the process besides keyword searches.
Resume screening is a recruitment tool used by organizations to analyze a lot of resumes. This recruitment software usually works hand in hand with, or even within, an Applicant Tracking System. Old Applicant Tracking Systems (ATS) were primarily used to hold applications and facilitate the entire hiring process. Modern recruitment software is more sophisticated and can perform many other tasks.
Essentially, the software is looking to determine one thing:
"How well does this person fit the criteria we’re looking for?"
The approach taken will be dependent upon the platform, with some relying on strict definitions and keywords, while others – powered by AI – may be able to consider context.
The screening process usually happens in several stages. It starts when a candidate submits a resume and ends with recruiters having a more organized list of applicants to review.
It all starts when the candidate applies for a certain job and sends in his/her CV.
The file may be a PDF, Word file, or any other format that the system supports. The document is received by the system and formatted to be analyzed. It might sound like a minor step, but formatting of the document matters in this case. In case the resume includes complex columns, strange graphics, images, or unreadable text, some data might not be extracted at all.
This is one of the reasons why a plain and readable resume is better than an overly designed one.
Next, the system uses resume parsing technology to understand the document.
Instead of keeping the CV as one large block of text, parsing software identifies different types of information and organizes them into structured fields.
It may extract:
The above structured format makes it much easier for recruitment software to search through this candidate profile.
In case the recruiter is looking for a candidate with "Python" experience, then the software won't have to look into each resume separately. It can search the information already extracted from the applications.
If you're wondering how does resume screening software work in practice, the process becomes clearer once you understand how the system reads, analyzes, and compares candidate information. After parsing the resume, the next thing that usually follows is matching.
The program analyses the job description and requirements set forth by the employer. They can be anything from skills, years of experience, education, certification, geographical location, to anything else. Let us consider the case where a company is recruiting an SEO specialist.
The employer is seeking:
Hiring Requirement | Example |
Experience | 2+ years |
Core skills | SEO, keyword research, link building |
Tools | Google Search Console, Google Analytics |
Education | Bachelor's degree preferred |
Additional skills | Content optimization |
The screening system can then compare these requirements against candidate profiles.
A candidate who has relevant SEO experience, keyword research knowledge, and several years of digital marketing work may appear more closely matched than someone with no related experience. And it’s here where the difference becomes apparent.
Older technologies often relied a lot on keywords.
If the job description of a company featured “social media marketing,” then that was what the system looked for in the resume. This works well enough, but there’s one flaw to it.
Skills are not described using identical terminology all the time. One individual can refer to the skill as “social media strategy,” another as “social media management,” and a third individual may choose the phrase “digital community management.”
There is a tendency among people not to use identical terms in describing identical skills. People may use different terminology like "social media strategy," "social media management," and "digital community management." All three terms may carry similar meanings despite being not identical.
With today's systems, one can leverage natural language processing and AI to find connections between words and the context in which certain skills are used.
For instance, having knowledge about "search engine optimization" may be useful for someone who is looking for people with "SEO" skills.
However, AI does not automatically make the system know everything. The quality of the job description, resume information, screening criteria, and technology itself all affect the outcome.
The system can assist recruiters in sorting out the candidates according to the employer's criteria after processing their resumes.
According to the program used, recruiters could do the following:
Some platforms may also assign scores or matching percentages.
However, such scoring should not immediately result in a final hiring decision. The reason for this is that the highest score does not always indicate the best performance in the real work process.
However, the above information may not be the whole picture when it comes to the applicant.
The main benefit is time.
Often, recruiters face the need to fill several vacancies simultaneously, and there may be hundreds or even thousands of resumes received in response to each position. Manual examination of all of them is simply impossible.
Other benefits include:
Software can process applications much faster than a person manually opening each CV.
Information on candidates can be kept in the form of profiles, which makes searching more efficient.
Recruiters can establish specific requirements before screening begins instead of making completely different judgments for every resume.
Recruiters can search their existing candidate database when a new vacancy becomes available.
Instead of spending hours doing the same initial screening task, recruitment teams can focus on more valuable parts of the hiring process. That's really the practical value of an ATS resume screening system — not replacing recruiters, but helping them handle application volume.
Indeed, and this is an important thing to know for both hiring companies and job applicants.
Resume screening software is not flawless. A suitable applicant may be overlooked due to poor resume writing that fails to convey the applicant's suitability or due to unusual wording or formatting.
In other instances, a prospective hire may have worked for five years in an area where they cannot precisely define their expertise in line with the employer's selection process.
On the issue of bias, automation can generate many challenges, such as when there is too much dependence on algorithms, which could lead to the emergence of further issues. This means that recruiters need to check the outcomes of the screening process from time to time.
An effective resume screening process begins with an effective job description.
A job vacancy with unclear responsibilities and unrealistic requirements cannot be transformed by resume screening software. It would be best for recruiters to first establish what really counts.
One way is to categorize requirements as follows:
The screening criteria should then reflect these priorities.
Additionally, recruiters need to use several resume samples to test the screening process. If great candidates keep getting filtered out, the process may be too strict.
Understanding how does resume screening software work can also help candidates create better resumes.
The main point is not to create a CV full of keywords. In fact, it is the wrong approach. Instead, candidates should make their relevant experience easy to identify.
A strong resume for an automated screening system should generally:
For instance, don’t say:
"Handling online marketing activities."
You could mention:
"SEO & content marketing efforts resulted in an increase in organic website traffic by 35%."
This gives recruiters as well as the screening software more relevant information. However, don't mirror the job description verbatim. You need to demonstrate what you've done.
Not exactly.
An ATS is a broader recruitment system used to manage candidates throughout the hiring process. Resume screening can be one feature inside an ATS or a separate capability within recruitment software.
An ATS may help with:
So, while the terms are sometimes used interchangeably, they aren't always referring to the same thing.
To understand how does resume screening software work in the future, it's important to look beyond simple keyword matching and focus on how AI evaluates skills, context, and overall candidate relevance. Recruitment technology is moving towards skill-, context-, and matching-oriented processes. As opposed to looking at whether a certain word appears in a resume, the new generation tools are designed to analyze whether the candidate's background is relevant to the position. AI can be used to help recruiters find patterns in huge amounts of candidate data. But there will still be a human element.
Hiring involves communication, personality, judgment, culture, motivation, and many other factors that can't always be understood from a resume alone. The smartest recruitment process isn't completely automated.
It's supported by automation where automation makes sense.
Knowledge of the working of resume screening software works will be beneficial for both recruiters and applicants. The technology can analyze resumes, categorize candidate details, extract skills of candidates, match applications against job requirements, and aid recruiters in making shortlists.
The main issue for employers is to select technologies that will not take human judgment out of the hiring process.
This is where Search O Pal can help modern hiring teams. Recruitment technology solutions like CV Shortlister can significantly ease the process of screening and shortlisting candidates in the recruitment cycle. The future of recruiting does not lie in choosing between people and technology. It lies in employing technology that aids in making the hiring process smarter.
