How to evaluate the answers consistently
- Score against a rubric, not a gut feel: define 3-5 criteria per competency before the first interview.
- Ask every candidate the same core questions - unstructured interviews are the single biggest source of noise in sales development representative hiring.
- Demand specifics: names of tools, numbers, constraints. Vague answers that survive one follow-up rarely survive three.
- Record evidence: tie every score to a quote. If you can't quote why someone scored high, the score is a bias.

Frequently Asked Questions
What are the most important interview questions for a sales development representative?
The highest-signal sales development representative questions target cold calling & email outreach techniques, objection handling & gatekeeping navigation, lead qualification & icp understanding through real scenarios the candidate has personally handled. Questions that ask candidates to reconstruct actual decisions - with constraints, trade-offs, and outcomes - predict performance far better than definitional or hypothetical questions.
How many interview questions should a sales development representative interview have?
Six to ten substantive questions in a 30-45 minute interview. Depth beats coverage: two or three adaptive follow-ups on each core question reveal more than a dozen surface questions. Structured interviews with consistent questions are among the strongest predictors of job performance in hiring research.
Can AI evaluate cold outreach and prospecting skills?
Yes. Candidates are asked to draft or role-play an outreach sequence for a given persona, and the AI evaluates their messaging, personalization, and follow-up cadence against what's known to actually drive replies. It also asks candidates to react to a "no response" scenario, testing persistence strategy rather than a single scripted attempt. This gives a much clearer signal than reviewing a resume line about "outbound experience."
How does AI interviewing handle high-volume SDR hiring?
An AI recruiting software solution interviews candidates in parallel, any time of day, with no scheduling coordination required - letting teams screen hundreds of SDR applicants in the time it would take to manually interview a dozen. Every candidate gets the same structured questions and the same evaluation criteria, so volume doesn't come at the cost of consistency. That's especially valuable for SDR roles, which typically generate the highest application volume of any go-to-market function.
