The hidden job market — how most roles are filled before they're advertised
If you've been searching job boards diligently and wondering why you're not finding the right thing — it might be because the right thing isn't there.
Research consistently suggests that a significant proportion of roles — estimates range from 50% to 70% — are filled without ever being publicly advertised. They're filled through networks, through referrals, through recruiters, through someone mentioning a name in the right room at the right time.
This is what's known as the hidden job market. And it's not a conspiracy. It's just how hiring actually works.
Why companies don't always advertise
Advertising a role is expensive and time-consuming. Reviewing hundreds of applications takes weeks. The process is uncertain.
If a hiring manager can solve the problem faster - by asking a trusted colleague for a recommendation, by calling a recruiter with a strong network, by reaching out to someone they've been wanting to hire - they will.
This isn't unfair. It's practical. And understanding it changes how you approach your job search.
What the hidden job market means for you
It means that applying to advertised roles is only part of the strategy. The other part - often the more effective part for senior and specialist roles - is being in the right conversations before the role exists.
This is not about nepotism or who you know in the traditional sense. It's about being professionally visible, maintaining genuine relationships, and making it easy for people who know your work to think of you when something relevant comes up.
How to access roles that aren't advertised
Talk to specialist recruiters in your field. A good recruiter will tell you what's coming before it's public. They'll put your name forward for roles that aren't listed yet. They're paid by employers, so there's no cost to you — and building a genuine relationship with one or two recruiters who know your market well is one of the most underutilised job search strategies I see.
Activate your network with intention. Not "I'm looking for a job, can anyone help?" — that's passive and puts the burden on others. Instead, reach out to specific people with specific conversations: former managers, colleagues from previous roles, clients, peers from industry events. Let them know you're exploring what's next and ask for their perspective on the market, or whether they know of anything that might be relevant.
Create a target company list. Identify 15-20 companies you'd genuinely want to work for. Follow them on LinkedIn. Understand what they're doing and where they're growing. Connect with people who work there. When a role does come up — advertised or not — you'll be a warm contact rather than a cold application.
Be findable. Keep your LinkedIn updated. Be clear in your headline and About section about what you do and what you're looking for. Recruiters searching for your skills need to be able to find you easily.
One thing worth knowing
The hidden job market doesn't mean the advertised market is worthless. For some roles and industries, job boards are very effective. The point is that relying solely on advertised roles - particularly at the senior or specialist end - means you're only seeing a fraction of what's available.
Use both. But don't underestimate the value of the conversations that happen before anything is posted.
