Due Diligence on Your Recruiter: What to Ask Before Signing
By Daniel Bryant · 24 August 2026
You run due diligence on every SaaS vendor, every commercial lease, every new hire. But when it comes to the person responsible for finding your next critical hire — your recruiter — most companies barely scratch the surface. A quick Google, a glance at the fee structure, and a handshake. That’s it.
I’ve been on both sides. I’ve placed candidates through Zionic Group, and I’ve hired recruiters myself when building teams. The gap between a good recruitment partner and a bad one isn’t marginal — it’s the difference between a hire that sticks for three years and one that’s gone in three months.
Questions You Should Be Asking
When evaluating a B2B SaaS recruitment firm, ask about their specialisation, placement retention rates, sourcing methodology, and how they handle exclusivity. A strong recruiter will explain their process clearly, provide references from similar engagements, and demonstrate genuine knowledge of the roles they fill — whether that’s a RevOps Manager or an Account Executive. Vague answers are a red flag.
Here’s the list I’d start with if I were vetting a recruiter today:
“What roles do you actually specialise in?” Not what their website says. What they’ve placed in the last six months. If they say they do everything from warehouse staff to C-suite SaaS, walk away. Generalist recruiters don’t understand the nuance of hiring a Customer Success Manager versus a Sales Engineer. The discovery process, the candidate profile, the market dynamics — they’re completely different.
“What does your sourcing process look like beyond LinkedIn?” Every recruiter uses LinkedIn. That’s table stakes. Ask about their database, their network depth, whether they use a dedicated CRM (we built Kolvera for exactly this reason), and how they reach passive candidates who aren’t actively job-hunting.
“What’s your placement retention rate at 12 months?” This is the question most recruiters hate. If they can’t answer it, they’re not tracking it. If they’re not tracking it, they don’t care about long-term outcomes. Any firm worth engaging should know this number and be willing to share it.
“Can I speak to a client who’s used you in the last 90 days?” Not a testimonial from 2022. A recent client. Ideally one who hired for a similar role.
“How do you handle candidates who don’t work out?” Ask about their guarantee period, their replacement policy, and what they do proactively to reduce early attrition. Good recruiters don’t just fill seats — they qualify fit.
Red Flags That Should Stop You Cold
I’ve seen companies get burned by the same patterns over and over. Here’s what to watch for:
- They push volume over quality. If a recruiter sends you 15 CVs in the first 48 hours, they’re not qualifying candidates — they’re carpet-bombing. You’ll waste more time reviewing bad fits than you would have spent sourcing yourself.
- They can’t articulate your ICP back to you. After a briefing call, a good recruiter should be able to describe your ideal candidate better than you described them. If they just parrot your job ad back, they haven’t added any value.
- They get defensive about metrics. Time-to-fill, offer-to-acceptance ratio, retention rate — these aren’t gotcha questions. They’re basic indicators of competence. Defensiveness is a tell.
- They’ve never worked in or around your industry. Recruiting for SaaS roles like SDR/BDR or Implementation Specialist requires understanding of ARR, sales cycles, onboarding complexity, and product-led motions. If your recruiter doesn’t know what NRR stands for, how are they going to assess whether a candidate understands it?
- Their contract is heavily one-sided. Exclusivity demands with no performance commitments. Rebate clauses buried in fine print. Payment terms that front-load risk onto you. Read the agreement like you’d read any vendor contract.
What Good Actually Looks Like
A recruiter who’s worth their fee does three things well. They narrow the funnel so you’re only meeting candidates worth meeting. They manage the candidate experience so your employer brand isn’t damaged by a sloppy process. And they give you honest market intel — including telling you when your salary band is wrong or your role title doesn’t match what the market expects.
The best engagements I’ve run through our services have always started with a proper briefing — not a job description email, but a real conversation about team structure, growth plans, what the last person in the role got right or wrong, and what success looks like at 6 and 12 months. That level of depth is non-negotiable.
Good recruiters also challenge you. If you’re asking for a Head of Customer Success but your ARR doesn’t justify the seniority, a decent recruiter will flag that and suggest alternatives. The ones who just nod and start searching are the ones who’ll waste your time.
