You do not need to understand the technology to screen a technical candidate well. You need to test whether the candidate's account of their own work holds up under specific follow-up questions — what they built, what their exact part was, what went wrong, and what they would do differently. That test works the same way whether the role is a cloud engineer, a structural engineer, or a lab scientist, because it is testing evidence quality, not technical correctness.
Software engineer phone screen questions covers one role in depth: exact questions and resume-inflation patterns specific to software engineering. This page is the underlying method, usable for any technical role you are screening, plus how to prepare for a role you know nothing about going in.
The recruiter's actual job: evidence quality, not technical correctness
You cannot judge whether a candidate's Kubernetes architecture was the right call, or whether their surgical technique was sound. You can judge whether they can describe it specifically, consistently, and with detail that would be hard to fake. That is a skill you already have from screening any role — the difference is knowing where to point it on a resume full of unfamiliar terms.
Before the call: a 15-minute prep routine
- Pull three to five must-have terms from the job description and look each one up long enough to know roughly what it does and how it relates to the others — not to master it.
- Ask the hiring manager one question in advance: "what would a strong answer to [the hardest requirement] sound like, in plain terms?" This single question, asked once at intake, is worth more than an hour of independent research.
- Write down two or three follow-up prompts tailored to the role's must-haves, using the universal patterns below rather than technical questions you cannot evaluate yourself.
- Note which claims you can independently verify — a certification number, a published project, a portfolio — separate from claims you can only assess by how they are explained.

These work across technical domains because they test how someone talks about their own work, not domain knowledge you would need to judge yourself.
| Question | What it tests | What a weak answer sounds like |
|---|---|---|
| "Walk me through your exact part in [the project on their resume]." | Individual contribution versus team credit | Stays at "we" throughout, cannot isolate a single decision they personally made |
| "What was the hardest technical decision on that project, and what were the options?" | Depth beyond the surface description | Names the decision but cannot describe any alternative they considered |
| "What went wrong, and how did you find out?" | Ownership and honesty; nearly every real project has something that went wrong | Claims nothing went wrong, or blames it entirely on someone else |
| "If you started that project again today, what would you do differently?" | Reflection and growth, hard to fake convincingly | Generic answer ("I'd plan better") with no specific change named |
| "Explain [the must-have term] to me as if I'm a new hire who has never heard of it." | Real understanding versus memorized vocabulary | Repeats jargon-heavy phrases without simplifying; gets circular or vaguer under a second ask |
Translating jargon into outcomes
When a candidate uses a term you do not know, do not nod and move on. Ask a short, neutral question that gets the outcome, not the definition: "and what did that let you do that you couldn't do before?" or "how did the team know that worked?" You are not asking them to re-explain the term — you are asking what changed because of it, which is a question you can evaluate regardless of the underlying technology.
Invented example — a candidate for a data engineering role:
Candidate: "I built a CDC pipeline into the warehouse."
Recruiter: "What did that let the team do that they couldn't do before?"
Candidate: "Before, the sales dashboard was a day behind — someone ran a batch job overnight. After, changes in the source database showed up in the dashboard within a few minutes, so the sales team stopped asking 'is this number from today.'"
You still may not know exactly what "CDC" (change data capture) means technically, but you now have a specific, checkable claim: a dashboard went from a day behind to a few minutes behind, and a named team stopped asking a specific question. That is evidence you can carry into a submittal or a debrief.
When to loop in a technical stakeholder
Not on the first call. Use your own screen to confirm role fit, seniority signals, communication, logistics, and the evidence-quality questions above. Bring in a technical stakeholder for candidates who pass that bar, and give them a narrow job: confirm the two or three claims you could not verify yourself, rather than re-running the whole interview. Ask the stakeholder in advance for the specific questions they want asked, and where possible, have them review your notes rather than sit on every call — their time is the scarcest resource in the process.
Reading a resume you don't fully understand
- Scope and scale, not tool names, are usually readable without technical knowledge. "Managed a team of 12" or "processed 2 million records a day" tells you something even if you don't know the stack.
- Progression tells a story. Titles and responsibilities that grow over time, even in an unfamiliar field, suggest sustained real work more reliably than a single impressive-sounding project.
- Certifications and licenses have public verification for most fields — professional engineering licenses, medical and clinical credentials, IT and cloud vendor certifications commonly have a lookup by number or name on the issuing body's site. Use it rather than taking the resume line as given.
- A skills list with no project or role tied to any of them is worth a direct question: "which of these have you used in the last year, on what kind of project?"
Red flags anyone can hear
| Pattern | Why it is a flag |
|---|---|
| More jargon when asked to simplify, not less | Genuine understanding usually gets clearer under a "explain it simply" prompt; bluffing tends to escalate |
| Cannot name a single mistake or setback on a project they led | Real project ownership almost always includes something that did not go as planned |
| Answers describe the team's work, never their own specific part | Common with candidates who were adjacent to strong work rather than doing it |
| Confident on breadth, vague on any one thing when you go deeper | A resume built from reading about a technology, not from using it |
| Certification claimed but the candidate cannot describe how it was obtained (exam, renewal, continuing education) | Worth a direct license lookup before moving forward |
A worked example: screening a role you don't know
Invented scenario: a recruiter with no clinical background screening a respiratory therapist role. Must-haves from the job description: active state license, ventilator management experience, ICU setting.
Prep (15 minutes): confirmed the state licensing board has a public lookup by license number; asked the hiring manager what "strong vent management experience" looks like in practice, and got back "can describe adjusting settings in response to a patient's blood gas results without prompting."
On the call: asked the candidate to walk through a specific recent case involving a ventilator adjustment — what the numbers were, what they changed, and how they knew it worked. The candidate described a specific blood gas reading, the exact setting change, and how the follow-up reading confirmed it.
Verification: license number checked against the state board's public lookup during the call, confirmed active and in good standing.
None of this required clinical training. It required knowing what a strong answer sounds like (from the hiring manager), asking for a specific case instead of a general description, and checking one fact independently instead of trusting the resume line.
What not to do
- Do not pretend to understand something you do not. Candidates notice, and it removes your ability to ask the simple follow-up question that actually tests understanding.
- Do not let a single impressive term substitute for a specific answer. "I've worked extensively with [technology]" is not evidence; a specific project with a specific outcome is.
- Do not rely on the candidate's self-rated skill level (1–10) as data. It correlates poorly with actual ability and mainly reflects confidence.
- Do not skip the license or certification check because the resume looks credible. The check takes minutes and is the one piece of hard verification available on many technical and licensed roles.
- Do not turn the screen into a technical quiz you found online. A list of trivia questions copied from a forum tests whether the candidate has seen that exact list before, not whether they can do the job, and a candidate who has genuinely done the work may stumble on a question phrased in an unfamiliar way.
A note on very senior technical roles
The method above covers most technical screening well, but a senior or staff-level technical hire usually needs a technical interviewer earlier in the process, not just at the deep-dive stage — the gap between "sounds strong to a non-technical ear" and "is actually strong at this level" gets harder to detect the more senior the role. Treat your own screen as filtering for the basics and communication, and be candid with the hiring manager about where your judgment reaches its limit for that particular role.
Questions people ask
Do I need to learn the technology to screen a technical role well?
No. You need to learn enough vocabulary to ask specific follow-up questions and to know when an answer is suspiciously vague, which is a few hours of preparation, not months of study.
What if a candidate uses jargon I don't understand?
Ask them to explain it as if you were a new team member, and listen for whether the explanation is consistent, specific and confident. Someone who genuinely knows a topic can usually explain it in plain language; someone who is bluffing tends to retreat into more jargon when asked to simplify.
Should a technical stakeholder always be on the call?
Not for a first screen. Bring one in for a technical deep-dive after your screen has confirmed the basics — role fit, seniority, communication, logistics — so their time is spent on candidates worth a deeper look.
How do I know if a certification is real and current?
Most licensing and certification bodies publish a public verification lookup. Ask the candidate for their certification number and check it yourself rather than taking the resume claim alone.
