Candidates sort recruiters into helpful and unhelpful. The more useful sort is by how they are paid, because that predicts behavior far better than personality does.
There are three models. Knowing which one you are dealing with tells you how fast they will push and whose side they are on when a number is being negotiated.
The three models
Contingency
An external agency paid only if their candidate is hired, usually a percentage of first-year base salary: often quoted at roughly 15% to 25%, though it varies by industry, and higher for senior or hard-to-fill roles. No placement, no fee.
Several agencies often work the same opening at once, against each other and the employer's own team. Their economics therefore depend on speed and volume. They are not paid for the twelve candidates who were not hired, which shapes everything they do.
Retained
The employer pays in installments regardless of outcome: often a third on engagement, a third at shortlist, a third on placement. Used for senior, specialized or confidential searches. The recruiter has exclusivity and is paid to run a thorough process, not win a race.
Retained recruiters move slowly, map a whole market, and will spend an hour with a candidate they are unsure about. If one contacts you, the role exists.
Internal
Salaried employees of the hiring company, often with a bonus linked to hiring targets or time-to-fill. No fee on your salary.
They are the most honest about the role, because they work with the hiring manager afterward, and the least able to advocate on your pay, because they represent the budget.
Why an agency recruiter pushes speed
A contingency recruiter competing with two other agencies is paid for being first with an acceptable candidate, not for being right with the best one. That produces recognizable behavior: submitting your resume within an hour, pushing an interview slot before you have read the job description, discouraging you from talking to other agencies about the same employer.
None of this is dishonest. It is the rational response to a fee that only pays on a win, in a market where another agency may submit the same candidate an hour earlier and take it.
It means two things for you. Their urgency is about their pipeline, not your interests. And never let a recruiter submit you anywhere without naming the company first. Duplicate submissions get candidates disqualified, and it is the most common way an application dies quietly.
Whose interest is served in a salary negotiation
The honest answer is more nuanced than the cynical one.
A contingency recruiter's fee is a percentage of your salary, so a higher offer pays them more. But the marginal fee difference between an offer of $70,000 and $75,000 is small, while the risk of the deal collapsing over that $5,000 is not. A recruiter making a few percent more on a placement that might not close will usually push you to accept.
Their interest aligns with yours on direction and diverges sharply on risk tolerance. They want a higher number in principle and a closed deal in practice; when those conflict the closed deal wins.
Retained recruiters are closer to neutral, since their fee is usually agreed before the search starts. Internal recruiters are managing a band and a budget, and while many genuinely advocate for you, they are not your agent.
So never treat a recruiter as your negotiator. Use them for information (the band, the comparators, what the hiring manager cares about) and make the actual ask yourself.
The one thing to control
Never let anyone submit your resume to a company you have not explicitly named and approved, and keep a written record of which agency sent you where and when. Duplicate submissions are the single most common self-inflicted wound in an agency-mediated search, and they are invisible. You simply never hear back.
How to work with them productively
- Be useful to their pipeline. A recruiter in your niche keeps coming back if you answer quickly, show up, and refer others when a role is not for you.
- Pick three or four specialists, not thirty generalists. Relationships with recruiters who own roles in your function are worth something. Being on many databases is not.
- Tell them your real number early. Not because they deserve it, but because a mismatch discovered at the offer stage wastes weeks. Give a range with a floor you mean.
- Keep your own pipeline. Their roles supplement your search rather than replace it. Waiting on a recruiter is the most common way a month disappears.
- Expect asymmetric communication. Responsive while you are live in a process, silent otherwise. That is capacity, not judgment.
Questions to ask on the first call
- Are you retained or contingency on this role, and is anyone else working it?
- Have you placed with this employer before, and how many rounds is their process?
- What is the budgeted range, and has anyone been rejected on salary yet?
- Why is the role open: growth, replacement, or a restructuring?
- What did the hiring manager say they are looking for, in their own words?
- What has gone wrong with the candidates they have already rejected?
The last is the most informative and the one most recruiters answer honestly. It tells you what the real filter is, which is frequently not what the job description says.
A recruiter is not your advocate and not your adversary. They are a broker whose fee depends on a transaction closing, and reading them that way makes them far more useful.
A note on fees
Fee percentages and the use of retained search vary by industry and seniority. One rule holds almost everywhere: legitimate recruiters are paid by the employer, not by you. The FTC's consumer guidance on job scams says honest placement firms do not typically charge candidates, and that a firm asking you for a fee, especially up front, is probably a scam. If someone asks you to pay to be represented, walk away.
