Recruiters are one of the most misunderstood parts of hiring. Candidates alternate between treating them as career advisors and dismissing them as time-wasters. Neither is right. They are intermediaries with their own incentives, and once you understand those incentives they become genuinely useful.
Know which kind you are dealing with
Internal recruiters work for the employer. They are filling specific roles at one company and their interest is a good hire at a sensible cost.
Agency recruiters work on behalf of employers but are paid on placement. Contingency agencies are paid only if their candidate is hired, so they move fast and submit widely. Retained search firms are paid regardless and work on a small number of senior roles.
The kind determines how they will treat you. A contingency recruiter may push you toward any role that fits; a retained one will be slower and more selective.
Understand who pays
In almost all cases the employer pays. That means the recruiter client is the employer, not you. They are not deceiving you by prioritising the client, that is the arrangement.
The practical implication: treat their advice as informed but interested. A recruiter telling you an offer is excellent may be right, and also has a fee attached to your acceptance.
Be direct about what you want
Vague candidates get sent vague opportunities. Give a specific target: role type, level, salary range, location or remote requirement, and any absolute constraints.
Being specific does not narrow your options, it filters out the noise that would otherwise consume your time.
Control where your details go
This is the most common problem candidates hit. Once your resume has been submitted to a company by one agency, another agency generally cannot present you, and you may be blocked from applying directly.
Insist that a recruiter names the company and gets your explicit approval before submitting you anywhere. A recruiter who refuses is one to stop working with.
Do not rely on a single channel
Agency recruiters cover a slice of the market, usually specific industries and levels. Many roles never go through an agency at all. Working with one or two good recruiters is sensible; treating them as your entire search is not.
Keep them updated, briefly
A recruiter with current information about your situation can act quickly when something suitable appears. Tell them when your circumstances change: a new offer in play, a shift in expectations, a decision to stop looking.
Short updates. They handle many candidates and value efficiency.
Judge them by how they behave early
Good signs: they ask about what you want before pitching, they know the client and the team, they explain the process and timelines, they give feedback after interviews.
Bad signs: pressure to accept, vagueness about the employer, submitting you without permission, disappearing after the interview. Those behaviours do not improve over time.
Stay useful to them
The relationship outlasts one search. Reply promptly, turn up to arranged calls, and refer people when you can. Recruiters remember candidates who made them look good, and they will bring the next opportunity to those people first.
