Why Hiring Vocabulary Matters
Job searching has its own language. When a recruiter emails about a passive opportunity, or a job board flags your resume as not passing ATS screening, it helps to know exactly what those phrases mean — and what they signal about your next move.
This reference covers the terms you're most likely to encounter during a US job search, from initial application through offer negotiation. Use it alongside our job search fundamentals guide if you're newer to the process, or dip in and out as specific terms come up.
ATS (Applicant Tracking System)
Software used by employers to collect, parse, and rank job applications automatically. Resumes that don't match the system's criteria may be filtered out before reaching a human reviewer.
Recruiter
A hiring professional — usually employed in-house — who sources, screens, and coordinates candidates for open roles within a single organization.
Headhunter
An external recruiter who works across multiple companies, typically targeting passive candidates for mid-to-senior roles. Also called an executive recruiter or search consultant.
Hiring Manager
The employee who will directly supervise the new hire. They define role requirements and usually have final say in the selection decision.
Active Candidate
A job seeker who is openly looking for new employment and actively applying to positions.
Passive Candidate
Someone currently employed who is not actively job hunting but may be open to the right opportunity. Recruiters often target this group.
Phone Screen
A brief introductory call — typically 15–30 minutes — used by recruiters to verify a candidate's basic qualifications and interest before scheduling a full interview.
Job Requisition
An internal document or request that formally opens a new job posting within a company. It defines the role's scope, budget, and requirements before the position is advertised publicly.
Offer Letter
A written document from an employer outlining the proposed terms of employment — including title, compensation, and start date. It is generally not a binding legal contract unless stated.
Non-Compete Agreement
A clause or separate document that restricts an employee from working for competing organizations for a defined period after leaving a job. Enforceability varies by state.
Talent Pipeline
A pool of pre-screened or known candidates an employer keeps on file for future openings, allowing faster hiring when new roles arise.
Counter-Offer
A response from a current employer — or a candidate — proposing revised terms (usually higher pay) when one party objects to the terms originally proposed.

The People Involved in Hiring
Recruiter vs. Headhunter: These two are often used interchangeably, but there's a real difference. A recruiter (also called a talent acquisition specialist) typically works in-house for a single employer and fills that company's open roles. A headhunter (or executive recruiter) is usually an external agent who works on behalf of multiple companies, often targeting candidates who aren't actively looking. Headhunters tend to focus on mid-to-senior roles and are compensated by the hiring company, not the candidate.
Hiring Manager: The person who will directly supervise the successful candidate. They define the role requirements and typically make the final call. Understanding their perspective is valuable — see what hiring managers actually do with your application for a detailed breakdown.
Active vs. Passive Candidates
You're an active candidate when you're openly searching and applying. You're a passive candidate when you're currently employed and not actively looking, but open to the right opportunity. Recruiters and headhunters frequently target passive candidates because they're perceived as lower-risk hires. Knowing which mode you're in helps shape your strategy — active vs. passive job searching covers this distinction in depth.
Application and Screening Terminology
Applicant Tracking System (ATS)
An ATS is software that employers use to collect, organize, and filter job applications before a human reviewer sees them. Most medium-to-large employers use some form of ATS. The system parses your resume for keywords, formatting, and qualifications, then ranks or screens out candidates automatically. This means a poorly formatted resume — even from a qualified applicant — can be eliminated before any human reads it.
To improve your chances, tailor your resume language to mirror the job description and avoid complex formatting like tables or text boxes. Our detailed guide on how ATS systems filter resumes walks through the specifics. You can also find resume and interview guidance in our Resume & Interviews hub.
Screening Call and Phone Screen
A short conversation — usually 15 to 30 minutes — conducted by a recruiter to verify basic qualifications, salary expectations, and availability before moving a candidate to a full interview. Treat it as a real interview: prepare concise answers and have questions ready.
Offer Letter vs. Employment Contract
An offer letter outlines the proposed terms of employment (title, salary, start date) and is typically not a legally binding contract. An employment contract is a formal legal document that may include clauses around non-compete agreements, severance, or intellectual property. Always read both carefully, and consult a qualified employment attorney if you have concerns about contract terms.
