Anyone can talk about resilience in an interview. Only some people can demonstrate it when you push back on them live. That is why the single best predictor question in an SDR interview is not "why do you want this job," it is asking the candidate to role-play a cold call objection in real time. How someone handles being told no, on the spot, with no time to prepare a polished answer, predicts the actual job better than any resume claim about grit or coachability. This guide is organized the way a strong interview process should be structured: screening questions that check motivation and coachability, skill questions that test research and communication, and a live role-play that reveals how someone actually behaves under the exact pressure the job applies daily. Whether you are interviewing for an SDR role or hiring for one, these are the questions that separate a good answer from a good hire.
SDR interview questions are the set of screening, skill-based, and role-play questions used to evaluate a Sales Development Representative candidate's coachability, research ability, communication skill, and resilience under real-time rejection, which together predict on-the-job performance more reliably than general behavioral questions alone.
These five questions filter for whether a candidate understands what the job actually involves and whether they take feedback well, the two traits that predict early success more than raw sales talent does.
These test the mechanical skills the job actually requires, not personality.
This is the single highest-signal portion of the interview, and it is worth more time than every other question combined.
A strong candidate should ask about the team's actual quota attainment rate, not just the stated OTE. They should ask what tools and data the team uses, since a rep working a clean, verified contact list has a materially different job than one manually hunting for contact details. They should ask about the typical ramp time and what support looks like during the first 90 days, and about the realistic promotion path to AE, including how long it typically takes and what specifically triggers it.
An interviewer who cannot answer these specifically is giving the candidate real information, just not the kind they intended to share.
For the harsh feedback question, a weak answer is "I took it professionally and improved." A strong answer names the specific feedback, the specific change made, and a specific result: "My manager told me my calls opened too slowly. I cut my opener from 30 seconds to 10 and my connect-to-conversation rate went up within two weeks."
For the objection role-play, a weak response pivots immediately to a scripted rebuttal without acknowledging what the prospect said. A strong response repeats back the objection in different words, asks one specific clarifying question, and only then offers a next step. This mirrors the real structure covered in our guide to cold call objection handling, and an interviewer familiar with that framework can score responses against it directly.
The Objection-Handling Proxy: how a candidate handles a live, unscripted objection during the interview predicts their on-the-job resilience and communication skill more reliably than any question about past resilience they answer from a script they had time to prepare. Weight this portion of the interview more heavily than polished, rehearsed answers to standard behavioral questions.
The reasoning is simple: a candidate has had time to prepare for "tell me about a challenge you overcame" long before the interview. Nobody prepares a polished response to being told "we already have a vendor" in the middle of a role-play they did not know the exact wording of in advance. The gap between how someone talks about resilience and how they actually perform under a real, live version of the job's core stress is the single most useful data point an interview can produce.
"Anyone can talk about resilience in an interview. Only some people can demonstrate it when you push back on them live."
If you are the candidate, practice the role-play format itself, not a script. Rehearsing how to stay calm and ask one clarifying question under pressure transfers directly to the interview and to the job itself.
Once hired, an SDR's actual day-to-day success depends heavily on whether the tools and data behind them are any good. A strong hire working a stale, unverified list will still struggle to hit quota, which is worth candidates asking about directly in the interview.
InboundLabs is a B2B contact database with buyer intent signals layered on firmographic data, giving new SDRs a way to filter by industry, headcount, region, and title instead of manually hunting for contact details during their most vulnerable ramp period. It holds a database of 280M verified B2B contacts with 98% email deliverability on verified contacts, plus verified direct dials, not switchboard numbers. Monthly plans, no annual lock-in, and free to start, no credit card required.

The best SDR interviews combine screening questions for motivation and coachability, skill questions for research and communication, and a live objection-handling role-play that reveals real resilience under real pressure. Weight that last stage most heavily, since it is the hardest part of the interview to fake and the closest simulation of the actual job. Whether you are hiring or interviewing, ask about real quota attainment and tooling, not just the headline numbers. A great hire still needs a clean list to succeed.

A live cold-call role-play with a realistic objection, such as "we already have a vendor for this." How a candidate handles an unscripted objection in real time predicts on-the-job resilience and communication skill more reliably than any prepared answer to a standard behavioral question about past challenges.
Ask about the team's actual recent quota attainment rate, not just the stated OTE, what data and tools the team uses for prospecting, typical ramp time and onboarding support, and the realistic path and timeline to promotion to Account Executive. Vague or evasive answers to these are meaningful red flags.
Give them a real company name and two minutes, then ask for one specific reason they would reach out. This tests real-time research speed and judgment directly, rather than relying on a candidate's self-reported claim that they are good at research.
Yes, and it should carry significant weight in the hiring decision. A live, unscripted objection-handling role-play reveals tone, listening skill, and composure under pressure in a way no behavioral question about past resilience can replicate, since the candidate has no time to prepare a polished response.
A candidate who cannot name a specific piece of feedback they received and a specific change they made in response, or one who pivots immediately to a scripted rebuttal during a role-play objection without acknowledging what the prospect actually said. Both suggest limited self-awareness and coachability.
A thorough process typically includes an initial screen, a skills and role-play round, and a final conversation, often spanning two to three weeks total. Rushing past the role-play stage to save time removes the single highest-signal portion of the entire process.

The title on the job post is a coin flip. Ask what the role actually rewards, and you will know what job you are being offered. In the convention most companies default to, a Sales Development Representative, or SDR, qualifies inbound demand that marketing already generated: content downloads, ad clicks,
Warm calls convert at 3 to 5x the rate of cold calls on the same ICP. A prospect who has seen your name once, an email, a LinkedIn view, a content download, is 3 to 5x more likely to engage on a call than one who has never heard of you. A 9am warm callback books a meeting at 35 to 50%, against 8 to
A voicemail that gets a callback is under 20 seconds, 8 to 13 being the sweet spot, follows a five-part structure, and is paired with a same-day email. But here is the honest framing: voicemail callback rates run 4 to 6% in mid-market US B2B SaaS, so a single message rarely produces a direct callbac
There is no blanket TCPA exemption for B2B calls. B2B calls and texts to wireless numbers are subject to the same TCPA restrictions as B2C. What B2B does get is a narrower carve-out: the FTC's Telemarketing Sales Rule exempts most B2B solicitation calls from the national Do Not Call registry, with a
