Most companies still hire the same way: write a job description, post it, and wait for applications to come in. It feels productive. The inbox fills up. There's a pile of CVs to review by Friday.
The problem is who's in that pile. The engineers actively applying to your role are, by definition, available right now. Some are excellent. But the people you most want - the senior backend engineer holding three systems together at a company you admire, the VP R&D who just shipped something hard - are not reading job boards. They're not unhappy enough to look. They're busy doing the work that made you want them in the first place.
That's what "passive candidate" actually means. Not someone who's lazy or hard to reach. Someone who isn't looking because they don't need to. And in Israeli hi-tech, that's most of the best people most of the time.
Why the best engineers are almost always passive
The strongest technical people in this market rarely hit the open market. When a great senior engineer decides to leave, they usually have an offer within their own network before a recruiter ever sees them. Their former managers call. Their old teammates, now at a new startup, reach out. The role gets filled in conversations you're not part of.
So when you post and wait, you're not fishing in the whole pond. You're fishing in the small corner of it that happens to be actively swimming past your hook this week. You can run a flawless process and still only ever see a fraction of the people who could do the job.
This is the single biggest reason searches stall. It's not that the talent doesn't exist. It's that the talent isn't applying.
Reaching people who aren't looking is a different skill
Sourcing passive candidates is not the same activity as reviewing applications, and it doesn't respond to the same effort. You can't post harder. You have to go and find specific people, understand what would actually move them, and open a conversation that respects the fact that they weren't asking for one.
That means three things have to be true at once. You need to know who the right people are - not a long list, the right twenty. You need a reason to reach out that's about them and their next move, not a copy-pasted pitch. And you need the seniority to have a real conversation when they reply, because a passive candidate's first question is rarely about salary. It's "why would this be better than what I already have?"
If the person reaching out can't answer that with judgment and context, the conversation ends there.
How we approach it at Once-HR
This is the part of recruiting we've put the most thought into, because it's where most searches are won or lost.
We start by mapping the market properly - the full landscape of who's doing this work in Israeli hi-tech, not just who's visible. Our sourcing agent does the heavy lifting here: it maps the market and surfaces passive candidates far beyond the obvious search, including people who'd never turn up in a standard keyword filter. That gives us reach no manual search could match in the same time.
But reach is only the start. Every outreach message is drafted to a specific person and reviewed by a founder before it's sent - never blasted. When someone replies, they talk to Inbal or Eva, not a junior coordinator reading from a script. That's deliberate. A senior engineer deciding whether to take a call gives you about one message to prove you understand their world. Founder-level judgment on that first exchange is what turns a passive candidate into an interested one.
The AI helps us cover more ground, faster, with more rigour. The humans decide what to do with it.
What this means for how you should think about hiring
If you take one thing from this, let it be this: the quality of your hire is capped by the quality of your pipeline, and your pipeline is capped by how far beyond the active market you're willing to go.
A few practical shifts follow from that.
Stop measuring a search by how many applications it generated. Volume from a job post tells you almost nothing about whether you'll make a great hire. Measure it by how many of the genuinely right people you got into a real conversation.
Be patient with the right outreach and impatient with the wrong process. Reaching twenty exact-fit passive candidates and getting five into conversation is worth more than two hundred inbound CVs you'll never read properly.
And get senior judgment involved early. The further up the seniority ladder a role sits, the more the first conversation matters, and the less it can be delegated to whoever has capacity.
The best engineers in Israeli hi-tech aren't waiting for your job post. The good news is they're reachable - if you go to them, with something worth their attention, and someone worth their time.
That's the whole game. Everything else is logistics.
Looking for the people who aren't looking? That's what we do. Talk to Inbal or Eva.
