Jobscan's Guide to Applicant Tracking Systems and How to Optimize Your Resume for Them

Applicant Tracking System Definition

Applicant tracking systems (ATS) are a type of software that act as a human resources database for organizing applicants. If you are familiar with customer relationship management tools (CRM), ATS are a close comparison, but with a particular focus on search. ATS are used by all sizes of companies to sift through large groups of job applicants, and to organize those applicants. The main goal of ATS are to act as a tool designed to simplify the life of the hiring manager or recruiter. Just like a search engine, after a recruiter's search, some applicant tracking systems rank applicants by keywords (skills, job positions) and filters (i.e. location and education). So, as an applicant, you should be optimizing your resume specifically to fit the job you are applying for.



Applicant tracking systems are designed to search resumes the same way a recruiter or hiring manager would. They are meant to take some of the workload off of the recruiter, so they try to mimic the process. When a recruiter or hiring manager receives a stack of resumes (or an inbox full), he or she will never have the time to read each one thoroughly. So, he or she can search for keywords related to the position they are looking to fill. ATS makes the searching much easier and automated to save time and avoid human error.


Why are Applicant Tracking Systems Used?

Applicant tracking systems are used to help ease the workload of recruiters and hiring managers. The internet makes it fast and easy for job seekers to apply for jobs. In fact, job board sites like Monster and Indeed allow job seekers to apply for a job using a saved resume with only one click.

Another key reason Applicant Tracking Systems are used is because of the law. The Internet Applicant rule was set in place to provide better recordkeeping of employees. The EEOC requires all companies with 100 or more employees to submit an EEO-1 report each September. The EEO-1 tracks employee race and gender information. ATS make the process of tracking information much easier.

Applying for jobs has become very easy for you, the job seeker, but daunting for the recruiter or hiring manager. Last year, Inc. reported that on average, a corporate job posting receives 250 applications. Of those 250 applicants, 4 to 6 will be contacted for an interview. The hiring manager/recruiter cannot possibly make the time to search through them all. ATS are the solution to their problem. While applicant tracking systems are not perfect, they are a good way for recruiters to hone in on top candidates.

ATS can also organize and save resumes for later. It is not only a filtering database, but a great organizational tool for hiring. Hiring managers can send emails directly to applicants to either inform them that they didn’t make the cut, or ask for an interview. Even if an application wasn’t the right fit for a certain position, recruiters and hiring managers can go back into the system later and pull up their application for a different position. If you’ve ever been contacted months later by a company you applied to, ATS is probably behind it. ATS stores applications even after the job has been filled.

How Do Applicant Tracking Systems Work?

Each applicant tracking system is slightly different. One might focus on the best possible keyword search capability, while another excels in resume parsing. Regardless of each ATS’s strengths and weaknesses, they all follow the same basic process.



When you apply through an ATS, you will most likely be asked to answer what are called “knockout questions”. Knockout questions can be in the style of check boxes or short answer, and their purpose is to narrow the pool of applicants immediately. If any of the knockout questions are answered unsatisfactorily, the resume will be flagged as rejected by the ATS. If you answer the knockout questions correctly, your resume will make it through to the next stage.

Recruiters/hiring managers can then search the resumes stored in the ATS by using keywords. These keywords are typically the exact same keywords used in the job posting. They could be based on skills, experiences, location, former employers or work experience. The image below shows a candidate search window from the perspective of the hiring manager/recruiter.

Because ATS store resumes, it is possible that you will be contacted for another position with the same company later on. If the keywords the recruiter/hiring manager uses to search for a different available position match with your resume, it is likely you could receive an interview. Recruiters and hiring managers can also make notes or star-rate about each candidate. If they have no negative feedback on their profile, they might be contacted later on.

Believe it or not, your social media profile can actually help your job search. Some ATS can use social media to search for potential employees. Certain ATS software searches through social media sites for keywords. So, update your profiles with common keywords for the job industry you are interested in, as well as your work experience, and you might just be contacted about a great job.


Applicant Tracking System Optimization

Applicant tracking systems are built to ease the job of the recruiter or hiring manager by narrowing the pool of applicants. So, you can’t expect any basic and generic resume to make it through. From knockout questions to keyword searches, there are plenty of opportunities for your resume to be rejected or lost in the shuffle. The fact is, you will not get an interview if your resume is not optimized against ATS.

ATS are not perfect. There are many good candidates whose resumes the recruiter/hiring manager might never see because they don’t include the correct keywords. However, ATS is great resource overall because it helps solve the problem of sorting through tons of resumes.

As a job seeker, you should get to know everything about ATS, and construct your resume based on the job posting for which you are applying. How you format your resume is also important. Tailoring your well formatted resume to applicant tracking systems and to the job you hope to get will raise your chances of getting an interview.

Applicant Tracking System Keywords

Keywords are easily the most important part of getting through ATS. Think of a keyword search in an ATS as a search engine, like Google. For example, if you want to find out when the 4th of July fireworks show is taking place, you might type into the Google search bar, “Fireworks”. Based on the keywords you typed in, the top search results matching both “fireworks” will appear. Many ATS use a Boolean search capability, which allows the searcher (hiring manager/recruiter) to combine search terms using AND, NOT and OR. For example, you will get more exact information about the fireworks show if you type in “Fireworks AND Chicago”. Similarly, if a hiring manager/recruiter types into the ATS keyword search bar, “Java AND New York City”, candidates whose resume mentions “Java” as a skill, as well as their location in New York City, will jump to the top of the applicant list.

Some ATS will rank candidates higher if a keyword is mentioned more than once. For example, a resume that lists “Java” two or three times throughout will rank higher on the list than one that only mentions it once. It can benefit you to list keywords more than once for this reason, but you should be careful not to take part in keyword stuffing.

An example of keywords stuffing is if you were to add in your resume, “Buffalo buffalo buffalo buffalo buffalo buffalo.” and change the text to white to hide it. Sure, it will be recognized as a complete sentence, but the hiring manager/recruiter will also see it as a lazy technique to get yourself to the top of the ATS list. Furthermore, some ATS highlight keywords in yellow, so it could be highlighted even if it is hidden.

Creating a “Skills” section on your resume is a great way to include relevant keywords in a natural way. Keywords that hiring managers and recruiters will search for are generally skills, location and work experience. When including skills, think hard skills vs. soft skills. Hard skills are concrete, such as “Spanish fluency”, “financial analysis”, and “Python”. Soft skills are important to the employer too, but they are better proved in person than on your resume. Soft skills include, “hard working”, “team player”, and “positive attitude”.

Customizing the keywords in your resume based on the job posting is very important. Read the job posting carefully and notice which keywords are relevant to the position and how often they repeat. If you have skills or experience that match those keywords, include them in your resume.

The challenge with customizing your resume is determining which information is necessary, and which information can be omitted. The best way to customize your resume is to use a tool that scans your resume and the job posting and recommends to you the keywords you need to get through ATS. Jobscan is one such tool that you can use for free and see real resume optimization results. Below you can test a sample resume and job description or input your own.
