Most outbound recruiting is set up to fail. Mass-blast 500 candidates a week, hope a few respond, burn the rest as future opportunities. The teams that win in talent-density searches treat every outbound message like an executive search at-bat: scarce, deliberate, never to be wasted. Chandler Martin built that operating model at Zocdoc.
Chandler Martin (Senior Director of People at Zocdoc) joined Nolan Church and Siadhal Magos on 10x Recruiting (more episodes on the 10x Recruiting hub) to break down the predictive hiring model that anchors hiring-manager expectations from day one, the at-bats framework that treats outbound as a finite resource, and the candidate-experience moves that win competitive searches in markets where the actual eligible pool is measured in single digits of thousands.
This recap covers the spreadsheet model Chandler shows hiring managers before any search starts, why talent pools are far smaller than most recruiters realize, how to run executive-search discipline on every senior hire, and the communication principle that prevents candidate doubt.
The predictive model that ends "we're not moving fast enough"
Most senior searches fall into a familiar pattern. The hiring manager wanted the hire yesterday, the recruiter starts sourcing, two weeks in the hiring manager is asking why there are not more candidates in the pipeline. The pressure is real but the diagnosis is wrong: the search is on track; the expectations were never set.
Chandler built a simple spreadsheet model that fixes this in a single intake conversation. The model uses historical conversion data to predict the full funnel before the search starts.
If I'm hiring for a senior ML search, top of the funnel is 26 candidates introduced. You're gonna take 16 hiring manager screens. We need two offers to get to one hire.”
The model is not complicated. It tracks historical conversion rates by role family, plots the expected weekly delta, and gives the hiring manager a "we are on track" or "we are off track" answer instead of vibes. The conversation shifts from "why aren't we moving faster" to "are we hitting the predicted weekly volume." Predictable inputs, predictable disagreements, predictable corrections.
Why most teams skip this: they default to playing defense the moment the req opens. Chandler's move is to take a beat at the start, build the forecast with the hiring manager in the room, and use it as the shared scorecard for the entire search.
At-bats are scarce: finite talent pools change the math
The math behind talent-density recruiting is brutal once you do it honestly. Roughly 1.2 million senior software engineers in the US. If you want the top 2%, that is 24,000 people total in the entire country. Real AI researchers globally? Roughly 844. The pool is small, every player gets messaged constantly, and every reach-out you send is a finite at-bat that you cannot get back.
Every time you outbound to someone, you're sort of burning your opportunity of future outbound to them.”
The teams that blast templated AI outreach across the full eligible pool are not just wasting effort; they are poisoning the well for every future search at their company. The candidate who got three generic InMails this month from your recruiter is the candidate who will never read the next message, even when it is the right role at the right moment. See ai-candidate-outreach-platforms for the wider state of the outreach market.
The framing shift: stop measuring outbound by volume. Start measuring it by reply rate, by interview-to-message ratio, by the percentage of messaged candidates who remember the company favorably 12 months later. The right number of outbounds per week per recruiter is much smaller than most teams assume.
Treat sourcing like executive search
For senior talent-density searches at Zocdoc, Chandler runs the playbook executive-search firms have used for decades: multi-touch sequences, tailored messaging, and a willingness to swap the sender if the senior candidate is more likely to respond to someone other than a recruiter.
Recruiters need to check their ego at the door. They might not be the person for the outreach for the senior ML engineer. That might be a CTO. That might be a CEO.”
This is the move most internal recruiting teams refuse to make. The recruiter owns the relationship, the recruiter owns the outreach, the recruiter owns the screen. For top-2% talent, that operating model fails by design. The senior engineer is not going to respond to a recruiter they have never heard of; they will respond to a CTO they have heard of in the technical community, or a CEO whose work they respect. The recruiter's job is to orchestrate, not to monopolize the outreach.

Speed means matching candidate preferences
Speed in recruiting usually means "move the candidate through the process faster." Chandler's reframe: speed means matching the pace and style of communication the candidate actually wants. The best candidates are playing offense. They are evaluating you as much as you are evaluating them. They want to understand the culture, the comp, the growth path, the team dynamics, the actual day-to-day work.
The Zocdoc move is to build a candidate-facing interview guide that anticipates the questions the senior candidate is going to ask. Write down what the process looks like, who they will meet, what each interview is designed to assess, what the comp ranges are, what the post-hire onboarding looks like. Hand it over before the candidate has to ask. The signal it sends is the signal you want them sending back: this team has its act together.
White-glove process is not a vanity move. It is a differentiator in a market where every other company is sending the same generic outreach and running the same generic loop.
Absence of communication breeds doubt
The principle Chandler operates by: in the absence of communication is doubt. When candidates do not hear from you, they assume the worst. When hiring managers do not hear from you, they assume the worst. The negative spiral kills momentum in exactly the searches where momentum matters most.
In the absence of communication is doubt.”
The mechanic that fixes it: the "no update update." Even when nothing has moved, send the note. "We do not have news yet. Here is what we are waiting on. You will hear from us by Friday." Six lines of email that prevent the candidate from drifting to the competitor offer they would have otherwise accepted by Wednesday.
Same logic applies to the hiring manager. Weekly update with the metric (vs the predictive model) prevents the "why aren't we moving faster" calls that consume an hour every time. Communication is cheap; the cost of its absence is enormous.
Where AI gives recruiting teams use
Chandler's playbook is a discipline play, but AI is what makes the discipline scalable. The teams that combine talent-density discipline with AI capture get the asymmetric advantage.
Metaview Notetaker captures every interview verbatim so the predictive model can be calibrated with actual conversion data, not memory. AI Sourcing identifies the actual eligible pool for a search so the at-bats are spent on the right candidates, not the easy-to-find ones. AI Outreach personalizes the multi-touch sequence using each candidate's actual background and prior touchpoints, not template tokens. Reports tracks the historical conversion rates that feed the predictive model. For the AI-augmented-recruiter operating shift, see claude-for-recruiters.
Numbers from the 2026 AI & Hiring Alignment Report. The 67% hire-quality stat is the one that maps to Chandler's at-bats thesis: when AI surfaces the right candidates first, your scarce outbound messages land on the candidates who actually convert.
The operating shift
Three concrete moves from Chandler's Zocdoc playbook for any team running talent-density searches:
One: build the predictive model before you open the search. Pull last year's conversion data by role family. Plot the expected funnel. Share it with the hiring manager at intake. Use it as the weekly scoreboard. The "we're not moving fast enough" conversations end the day the model goes live.
Two: stop blasting outbound; treat every message as a finite at-bat. Calculate the size of the actual eligible pool for the role. Cut the message volume by 50%. Double the personalization. Track reply rate, not send volume. Swap in the CTO or CEO as the sender when the recruiter is not the right person.
Three: install the "no update update." Every candidate, every hiring manager, every week. Even when nothing has moved. Six lines of email that prevent the doubt spiral. The teams that do this consistently win the close more often than the teams with better comp packages.
The TA teams that internalize these three moves will outperform the ones still running the 2022 outbound playbook. That is the operating shift.

Frequently asked questions
What does Chandler's predictive hiring model look like in practice?
A simple spreadsheet that uses historical conversion rates by role family to predict the full funnel before the search starts. For a senior ML search: 26 candidates contacted, 16 hiring manager screens, 2 offers, 1 hire. The model anchors hiring-manager expectations at intake and gives the team a weekly on-track vs off-track read instead of relying on hiring-manager vibes.
How small is the actual eligible pool for senior tech hires?
Smaller than most recruiters think. Roughly 1.2 million senior software engineers in the US total. The top 2%, the pool that talent-density teams compete for, is about 24,000 people. Real AI researchers globally? Roughly 844. Every outbound message is a finite at-bat against that pool, and burning the at-bat with templated AI outreach is a long-term reputational cost.
When should a CTO or CEO send outreach instead of the recruiter?
For any top-2% talent search where the candidate is more likely to respond to a known industry name than to an unknown recruiter. The recruiter owns the orchestration and follow-up; the executive owns the first-touch outreach. This is the executive-search playbook applied to internal recruiting, and it works because senior candidates trust people they have heard of in their technical community.
What is the "no update update"?
A short email to the candidate or hiring manager saying "we do not have news yet, here is what we are waiting on, you will hear from us by [date]." Sent on the cadence the recipient expects. It prevents the doubt spiral that kills competitive searches. Communication is cheap; the cost of its absence (candidates drifting to competitor offers, hiring managers losing faith) is enormous.
Why does Chandler emphasize candidate-facing interview guides?
Because the best candidates are playing offense. They are evaluating the company as much as the company is evaluating them. A guide that explains the process, the people they will meet, the comp range, and the post-hire onboarding sends a signal that this team has its act together. White-glove process is a differentiator in a market where every other company sends generic outreach and runs a generic loop.
