It analyzes keywords, years of experience, qualifications, location, and CV format to help streamline the process.<br\/> <br\/><br\/><br\/> <\/p>\n\n<p class=\"wp-block-paragraph\">Its growth has a fairly practical explanation. The volume of applications per job posting has grown by <a href=\"https:\/\/high5test.com\/resume-statistics\/\">182% since 2021 (High5Test),<\/a> yet HR teams&#8217; time remains limited. As a result, <a href=\"https:\/\/airesume.guru\/es\/blog\/estadisticas-curriculum\">between 70% and 75% of large organizations already use an ATS.<\/a> And not just to filter candidates out: it&#8217;s also used to manage communications, interviews, and much of each application&#8217;s journey.   <\/p>\n\n<p class=\"wp-block-paragraph\">On <a href=\"https:\/\/www.newtandem.com\/en\/blog\/\">our blog <\/a>you&#8217;ll find more content on how to prepare a recruitment process from start to finish.<br\/><br\/><\/p>\n<style>.wp-block-kadence-advancedheading.kt-adv-heading11578_d63472-b0, .wp-block-kadence-advancedheading.kt-adv-heading11578_d63472-b0[data-kb-block=\"kb-adv-heading11578_d63472-b0\"]{font-style:normal;}.wp-block-kadence-advancedheading.kt-adv-heading11578_d63472-b0 mark.kt-highlight, .wp-block-kadence-advancedheading.kt-adv-heading11578_d63472-b0[data-kb-block=\"kb-adv-heading11578_d63472-b0\"] mark.kt-highlight{font-style:normal;color:#f76a0c;-webkit-box-decoration-break:clone;box-decoration-break:clone;padding-top:0px;padding-right:0px;padding-bottom:0px;padding-left:0px;}.wp-block-kadence-advancedheading.kt-adv-heading11578_d63472-b0 img.kb-inline-image, .wp-block-kadence-advancedheading.kt-adv-heading11578_d63472-b0[data-kb-block=\"kb-adv-heading11578_d63472-b0\"] img.kb-inline-image{width:150px;vertical-align:baseline;}<\/style>\n<h2 class=\"kt-adv-heading11578_d63472-b0 wp-block-kadence-advancedheading\" data-kb-block=\"kb-adv-heading11578_d63472-b0\"><strong>How the ATS filters candidates<\/strong><\/h2>\n\n<p class=\"wp-block-paragraph\">The system looks for matches between the job posting and the r\u00e9sum\u00e9. If the vacancy requires experience in &#8220;payroll management,&#8221; for example, that exact phrase can make a difference. The key is to describe your real skills naturally, not to fill your CV with keywords out of context.  <\/p>\n\n<p class=\"wp-block-paragraph\">Format also matters. Columns, graphics, or images with text can make automated reading difficult, so a simple PDF or Word document is usually a safer choice. It may not be as visually striking, but it helps ensure the information gets where it needs to go.  <\/p>\n\n<p class=\"wp-block-paragraph\">Beyond this initial screening, many ATS platforms can also handle interview scheduling, send communications, organize databases, and support data protection compliance.<\/p>\n\n<p class=\"wp-block-paragraph\">Its main advantage is clear: <strong>it saves time and cost<\/strong>, maintains consistent criteria, and keeps a record of the process. That said, the outcome depends <strong>on proper configuration and human oversight<\/strong>. <\/p>\n<style>.wp-block-kadence-advancedheading.kt-adv-heading11578_cc4ce1-5a, .wp-block-kadence-advancedheading.kt-adv-heading11578_cc4ce1-5a[data-kb-block=\"kb-adv-heading11578_cc4ce1-5a\"]{font-style:normal;}.wp-block-kadence-advancedheading.kt-adv-heading11578_cc4ce1-5a mark.kt-highlight, .wp-block-kadence-advancedheading.kt-adv-heading11578_cc4ce1-5a[data-kb-block=\"kb-adv-heading11578_cc4ce1-5a\"] mark.kt-highlight{font-style:normal;color:#f76a0c;-webkit-box-decoration-break:clone;box-decoration-break:clone;padding-top:0px;padding-right:0px;padding-bottom:0px;padding-left:0px;}.wp-block-kadence-advancedheading.kt-adv-heading11578_cc4ce1-5a img.kb-inline-image, .wp-block-kadence-advancedheading.kt-adv-heading11578_cc4ce1-5a[data-kb-block=\"kb-adv-heading11578_cc4ce1-5a\"] img.kb-inline-image{width:150px;vertical-align:baseline;}<\/style>\n<h2 class=\"kt-adv-heading11578_cc4ce1-5a wp-block-kadence-advancedheading\" data-kb-block=\"kb-adv-heading11578_cc4ce1-5a\"><strong>How the human eye filters candidates<\/strong><\/h2>\n\n<p class=\"wp-block-paragraph\">This is where something that no automatic filter fully understands comes into play: <strong>context<\/strong>. A career change between industries, a career path with pauses, a self-taught background, or experience that doesn&#8217;t exactly match the job title can make a lot of sense when someone looks at it closely. <\/p>\n\n<p class=\"wp-block-paragraph\">A recruiter can also assess motivation, communication style, and team fit. You&#8217;ve probably experienced this: on paper, two applications look similar, but once you talk to the candidates, the perception changes completely. <\/p>\n\n<p class=\"wp-block-paragraph\">Even so, <strong>human review isn&#8217;t infallible either.<\/strong> The first read of a CV lasts between <strong>7 and 30 seconds,<\/strong> and fatigue, pressure, or unconscious bias can all play a role. Without shared criteria, two professionals can reach very different conclusions when reviewing the same profile. <\/p>\n<style>.wp-block-kadence-advancedheading.kt-adv-heading11578_039588-45, .wp-block-kadence-advancedheading.kt-adv-heading11578_039588-45[data-kb-block=\"kb-adv-heading11578_039588-45\"]{font-style:normal;}.wp-block-kadence-advancedheading.kt-adv-heading11578_039588-45 mark.kt-highlight, .wp-block-kadence-advancedheading.kt-adv-heading11578_039588-45[data-kb-block=\"kb-adv-heading11578_039588-45\"] mark.kt-highlight{font-style:normal;color:#f76a0c;-webkit-box-decoration-break:clone;box-decoration-break:clone;padding-top:0px;padding-right:0px;padding-bottom:0px;padding-left:0px;}.wp-block-kadence-advancedheading.kt-adv-heading11578_039588-45 img.kb-inline-image, .wp-block-kadence-advancedheading.kt-adv-heading11578_039588-45[data-kb-block=\"kb-adv-heading11578_039588-45\"] img.kb-inline-image{width:150px;vertical-align:baseline;}<\/style>\n<h2 class=\"kt-adv-heading11578_039588-45 wp-block-kadence-advancedheading\" data-kb-block=\"kb-adv-heading11578_039588-45\"><strong>ATS vs. human eye: quick comparison<\/strong><\/h2>\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>AXIS<\/strong><\/td><td><strong>ATS<\/strong><\/td><td><strong>HUMAN EYES<\/strong><\/td><\/tr><tr><td>Speed and volume<\/td><td>Very high<\/td><td>Limited<\/td><\/tr><tr><td>Objectivity<\/td><td>Consistent but rigid<\/td><td>Contextual but subjective<\/td><\/tr><tr><td>Detection of potential<\/td><td>Low<\/td><td>High<\/td><\/tr><tr><td>Bias risk<\/td><td>Data\/configuration bias<\/td><td>Unconscious bias<\/td><\/tr><tr><td>Cost<\/td><td>Lower operating cost<\/td><td>Greater dedication to people<\/td><\/tr><tr><td>Candidate experience<\/td><td>Fast but impersonal<\/td><td>Slow but personable<\/td><\/tr><\/tbody><\/table><\/figure>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"wp-block-paragraph\">The question, then, isn&#8217;t about choosing between technology or people.

However, like any automated system, it has its limits: it analyzes keywords and structured data, but it can&#8217;t capture nuance, context, or potential beyond what the r\u00e9sum\u00e9 itself reflects.  <\/p>\n\n<p class=\"wp-block-paragraph\">That&#8217;s why at New Tandem we don&#8217;t use these kinds of automated filters: we prefer professional analysis and a human touch to guide every recruitment decision. This allows us to evaluate each candidate individually, give opportunities to profiles that an algorithm would reject for not fitting a predefined template, and ensure fairer, more personal recruitment processes tailored to the real needs of each company and each person. That said, even though we don&#8217;t use these ATS filters, we do rely on profile management tools to centralize all information, making the more methodical tasks easier to carry out.  <\/p>\n\n<hr class=\"wp-block-separator has-text-color has-theme-palette-1-color has-alpha-channel-opacity has-theme-palette-1-background-color has-background\" style=\"margin-top:0;margin-bottom:0\"\/>\n\n<p class=\"wp-block-paragraph\"><\/p>\n<style>.wp-block-kadence-advancedheading.kt-adv-heading11578_d06e9d-ee, .wp-block-kadence-advancedheading.kt-adv-heading11578_d06e9d-ee[data-kb-block=\"kb-adv-heading11578_d06e9d-ee\"]{text-align:center;font-style:normal;}.wp-block-kadence-advancedheading.kt-adv-heading11578_d06e9d-ee mark.kt-highlight, .wp-block-kadence-advancedheading.kt-adv-heading11578_d06e9d-ee[data-kb-block=\"kb-adv-heading11578_d06e9d-ee\"] mark.kt-highlight{font-style:normal;color:#f76a0c;-webkit-box-decoration-break:clone;box-decoration-break:clone;padding-top:0px;padding-right:0px;padding-bottom:0px;padding-left:0px;}.wp-block-kadence-advancedheading.kt-adv-heading11578_d06e9d-ee img.kb-inline-image, .wp-block-kadence-advancedheading.kt-adv-heading11578_d06e9d-ee[data-kb-block=\"kb-adv-heading11578_d06e9d-ee\"] img.kb-inline-image{width:150px;vertical-align:baseline;}<\/style>\n<h3 class=\"kt-adv-heading11578_d06e9d-ee wp-block-kadence-advancedheading\" data-kb-block=\"kb-adv-heading11578_d06e9d-ee\">Are you looking for a recruitment process tailored to your needs, with a personal touch?<\/h3>\n\n<div class=\"wp-block-buttons is-content-justification-center is-layout-flex wp-container-core-buttons-is-layout-fe48e5de wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button has-custom-width wp-block-button__width-75\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/www.newtandem.com\/en\/contact-new-tandem\/\">Contact us<\/a><\/div>\n<\/div>\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>An ATS (Applicant Tracking System) is software that centralizes applications and automates part of the initial screening.
