What is an ATS? The Complete Guide to Candidate Tracking Systems in 2026

What is ATS and why is it essential in modern recruitment

ATS is the acronym forApplicant Tracking System, translated into Romanian asCandidate Tracking System. In simple terms, an ATS is a software platform that centralizes and automates the entire recruitment process - from the publication of a job ad to the signing of the employment contract.

Think of an ATS as an ERP dedicated to the HR and recruitment department. Just as an ERP system integrates finance, logistics and production in a single platform, an ATS integrates all activities related to attracting, evaluating and hiring candidates. Every CV received, every email sent, every interview note and every decision is recorded and accessible in one place.

Piata globala a solutiilor ATS a atins 3.28 billion dollars in 2025, according to industry reports, and continues to grow by more than 6% annually. This growth is not accidental - it reflects a real need. In the context in which the labor market is becoming increasingly competitive, companies that recruit efficiently have a significant advantage over those that still rely on manual methods.

The most relevant statistic is this:89% of large companies(over 500 employees) already use an ATS. But what surprises is that65% din IMM-uri(small and medium-sized companies) have not yet adopted such a system - although they are the ones that would benefit the most from automation, having smaller HR teams and limited resources.

How an ATS works: from job posting to hiring

A modern ATS covers every stage of the recruitment process. Let's go through the complete flow, step by step, to understand how each phase transforms.

Etapa 1: Publicarea jobului.Everything starts with the creation of the job advertisement. In an ATS, you define the position title, role description, mandatory and optional requirements, salary and location. Then, with a single click, the job is published simultaneously on several platforms - the company website, LinkedIn, BestJobs, eJobs and other recruitment portals. Without an ATS, this step involves logging in separately on each platform, copying the text and managing each ad individually.

Etapa 2: Colectarea aplicatiilor.As candidates apply, their CVs are automatically collected in a centralized database. It doesn't matter if they applied through LinkedIn, through the company website or by sending an email - all applications arrive in the same place, with automatically extracted information (name, contact, experience, skills). This elimination of data silos is one of the biggest advantages of an ATS.

Stage 3: Screening and filtering.This is where the actual automation comes in. The ATS analyzes each CV and compares it with the job requirements. Candidates are automatically classified according to the degree of suitability, and those who do not meet the minimum criteria can be automatically rejected with a personalized message. An ATS with integrated AI, like Treegarden, goes even further - it calculates a compatibility score and identifies relevant skills even if they are not expressed exactly as in the job description.

Etapa 4: Gestionarea pipeline-ului.Once filtered, qualified candidates enter the recruitment pipeline. Each candidate goes through defined stages (screening, interview, evaluation, offer) and the entire recruitment team can see in real time what stage each candidate is at. Comments, grades and evaluations are centralized on the candidate's profile.

Etapa 5: Programarea interviurilor.The ATS simplifies scheduling interviews by integrating with calendars (Google Calendar, Outlook), automatically sending invitations and confirming participation. Some systems, including Treegarden, also offer automatic generation of interview questions based on the candidate's profile and role requirements.

Stage 6: Decision and employment.After the interviews, the team evaluates the candidates using standardized scorecards. The ATS aggregates all evaluations, facilitating objective comparison. Once the winning candidate is selected, the platform can generate the offer and manage the onboarding process.

Who needs an ATS and when is the right time

The short answer: any company that employs more than 5-10 people per year benefits from an ATS. But let's be more specific:

Fast growing startups- If you are a startup that has passed the initial phase and is starting to grow, the recruitment volume increases exponentially. Without a structured system, you lose candidates, double the effort and create an inconsistent experience. An ATS helps you scale recruitment without adding HR staff.

SMEs with small HR teams- When a single HR specialist manages everything - from recruitment to personnel administration - automation is not a luxury, but a necessity. An ATS takes over 60-70% of the manual recruitment work, freeing up time for strategic activities.

Companies with seasonal recruitment- Retail, HoReCa or logistics companies have recruitment peaks in certain periods. An ATS allows the efficient management of large volumes of applications without the need for temporary HR personnel.

Organizations with several locations- When recruiting for offices in different cities or countries, a centralized ATS ensures consistency of the process and visibility at the organization level.

Key functionalities to look for in an ATS

Not all ATS solutions are created equal. Some are simple glorified databases, while others are complete platforms that automate every aspect of recruiting. Here are essential features to look for:

Publicare multiplatforma.The ability to publish a job on several portals simultaneously (LinkedIn, BestJobs, eJobs, own website) from one place. This functionality saves hours of work and ensures the consistency of the announcements.

Pipeline personalizabil.The stages of the recruitment process differ from company to company. A good ATS allows complete customization of the pipeline - adding, deleting or renaming stages according to the specific needs of the organization.

Automatizare email.Automatic sending of emails at each stage change (application confirmation, interview invitation, rejection, offer). This eliminates manual communication and ensures that no candidate is left without an answer.

Collaboration tools.In recruitment, decisions are rarely made by one person. An ATS allows multiple team members to evaluate candidates, leave comments, assign scores and participate in the selection process - all centralized on the candidate's profile.

Reports and analyses.Concrete data about the recruitment process: average hiring time, source of the best candidates, conversion rate at each stage, cost per hire. This information allows the continuous optimization of the recruitment strategy.

GDPR compliance.In Europe, the management of candidates' personal data must comply with the GDPR regulation. An ATS ensures the automatic deletion of data after the legal period, the collection of consent and the right to be forgotten - things that are almost impossible to manage manually.

Concrete benefits: numbers and statistics that matter

Adopting an ATS isn't just a matter of convenience - it's a decision with measurable financial impact. Let's analyze the numbers:

Reduction of employment time by 40%.Industry studies show that companies using an ATS reduce the average time-to-hire from 42 days to approximately 25 days. This 40% reduction means that vacant positions are filled more quickly, reducing the impact on team productivity.

Elimination of the loss of candidates.A frequently cited study in the industry shows that92% of candidates abandon complex application processes. An ATS with an optimized application form (on average 5 fields vs. 15+ in traditional forms) dramatically reduces the abandonment rate.

Saving time in screening.An HR specialist spends an average of 23 hours per week on manual screening. With an ATS, this time drops to 5-7 hours - a saving of over 70%. On the scale of an HR team of 3 people, we are talking about over 48 hours recovered weekly.

Improving the candidate experience.Candidates who receive quick responses and professional communication have a significantly better image of the company. In a job market where good candidates have more options, the recruiting experience can make the difference between attracting or losing top talent.

Data for informed decisions.Without an ATS, most companies do not know the answer to essential questions: What is the main source of qualified candidates? How long does a hiring process take on average? What are the stages in which we lose the most candidates? An ATS provides these answers automatically, allowing continuous optimization.

ATS versus traditional recruiting methods

Many HR managers still hesitate to adopt an ATS, considering that the existing methods "work quite well". Let's compare the two objective approaches:

Email and shared folders.The classic method involves receiving CVs by email, saving them in folders on Google Drive or SharePoint and communicating about candidates via email or chat. The problems: no unique version of the truth (everyone has a different copy), the impossibility of seeing the status of candidates in real time, the risk of losing CVs, zero automation.

Excel and Google Sheets.A step ahead of email, but with severe limitations: it does not support real-time collaboration (editing conflicts), it cannot store CVs or documents, it does not send automatic emails, it does not offer a visual pipeline and it becomes impossible to manage more than 50-100 candidates. In addition, GDPR compliance is almost impossible in a spreadsheet.

ATS modern.It centralizes everything in one place, automates repetitive tasks, provides complete visibility over the pipeline, ensures consistent communication with candidates and generates automatic reports. It's the difference between driving with a paper map and using GPS - both get you to your destination, but one is incomparably more efficient.

Another important factor:only 28% of current ATS users are satisfied with their solution. This statistic reflects the fact that many companies use outdated systems, too complex or unsuitable for their needs. Choosing the right ATS is as important as the decision to adopt one.

Why Treegarden is the right choice for the Romanian market

The ATS solutions market is dominated by international providers (Greenhouse, Workable, Lever, SmartRecruiters) that offer excellent products, but which are not always suitable for Romanian companies. Here's why Treegarden is worth considering:

AI integrat nativ.Unlike many ATSs that offer AI as an expensive add-on, Treegarden has artificial intelligence built into the core of the platform. AI Match Score, intelligent auto-reject and automatic interview question generation are available from the start, not as additional premium modules.

Affordable price for SMEs.While Greenhouse starts at $6,000/year and SmartRecruiters can reach $75,000, Treegarden offers comparable functionality at a fraction of the cost. It is designed for companies that want a professional ATS without a corporate budget.

Implementare rapida.You don't need an implementation consultant or weeks of configuration. Treegarden can be operational in less than a day - you create the account, configure the pipeline, publish the first job. Simplicity does not mean lack of functionality, but a user experience designed for efficiency.

GDPR-ready from the start.Compliance with the European data protection regulation is incorporated into the architecture of the platform. Candidates' consent, data retention, right to erasure - all are managed automatically, eliminating the risk of sanctions.
