How the 5-factor model is weighted

Communication — 30%
Outbound Experience — 25%
Coachability — 20%
Trajectory — 15%
Domain Fit — 10%

Each factor predicts a different aspect of on-the-job success. Communication and Outbound together account for 55% of the score because they're the hardest to teach and have the highest correlation with pipeline generation.

💬

Communication

Verbal clarity, active listening, written quality, and ability to adapt tone. SDRs spend 6–8 hours a day communicating — this is the #1 predictor of booked meetings.

Weight: 30% of total score

No real example, vague answer
2
Basic story, unclear what they did
3
Solid story with a clear structure
4
Specific hook, objection, booked outcome
5
Teaches you something, unprompted self-analysis
✅ Green FlagsMentions a specific personalized opener; explains WHY they adapted mid-call; references the outcome (meeting booked); shows self-awareness about what made it work.
🚩 Red FlagsCan't recall a specific call; says "I just followed the script"; focuses on luck rather than skill; no outcome mentioned.
2
Role-Play
"Pitch me your last product as if I'm a cold prospect. I'll give you 60 seconds starting now."
Scoring Rubric

3
Clear opener, benefit-focused, asks for time
4
Strong hook, handles interruption, direct ask
5
Compelling, confident, natural, closes for meeting
✅ Green FlagsLeads with a pain/outcome (not product features); confident and conversational tone; handles your "I'm busy" objection; asks for a specific next step.
🚩 Red FlagsStarts with "Hi my name is… our company does…"; reads robotically; can't handle one objection; ends with "does that make sense?" rather than booking.

Scoring Rubric
1
No example or one-word answer
2
Vague story, unclear change made

Sends another pitch email
3
Polite reply, asks for reason
4
Quick value re-framing + specific ask
5
Empathetic, curious, uncovers a use case, re-books
✅ Green FlagsDoesn't re-pitch; instead asks a diagnostic question ("Is it timing, or is [problem] not a priority right now?"); offers an easy next step; keeps door open.
🚩 Red FlagsSends the same pitch again; immediately moves on; uses passive-aggressive language; says "no worries" and closes the thread.
5
Written Sample
"Write a cold outreach email to a VP of Sales at a 50-person SaaS company. You have 5 minutes."
Scoring Rubric
1
Wall of text, no personalization

Short but generic, weak CTA

Clear, concise, relevant CTA
4
Personalized opener, pain-led, single CTA
5
Hyper-specific, provocative first line, effortless reply CTA
✅ Green FlagsSubject line under 8 words; first line mentions something specific about the prospect; body under 75 words; CTA is a yes/no question or calendar link.
🚩 Red Flags"I hope this email finds you well"; lists 4+ features; ends with "Would you be available for a 30-minute call sometime next week to learn more?"
📞

Outbound Experience

Cold calling volume, email sequencing, tools used, and measurable pipeline results. Covers the tactical execution layer of SDR work — what they've actually done, not just what they know.

🚩 Red Flags"I'd mark it closed-lost" after 6 attempts; has no recycling system; says "if they wanted to talk to me they'd have responded."
🧭

Coachability

How candidates receive, process, and apply feedback. SDRs who are coachable improve 2–3x faster than those who resist. This is especially critical for first-year reps.

Tries the new approach for a week
4
Tests both, tracks results, brings data back

A/B tests, shares findings with manager, iterates together
✅ Green FlagsTries the shorter opener without debate; tracks results over a meaningful sample; comes back with data rather than opinion; frames it as a collaboration.

🚩 Red Flags"I don't really read sales books"; names a resource but can't explain one thing they took from it; relies entirely on employer-provided training.
15
Situational
"A top-performing peer handles objections differently from you — and they're getting better results. What do you do?"

1
Defends their approach, dismisses
2
Watches without changing
3
Asks to shadow, considers adopting
4
Actively learns it, tests it
5
Studies it, adapts it to their style, shares back
✅ Green FlagsProactively asks to shadow or co-listen; curious about the WHY behind their peer's approach; willing to change their own style if data supports it.
🚩 Red Flags"Everyone has their own style"; dismisses better results as luck; says "I'll stick with what works for me" even without evidence it's better.
🚀

🚩 Red FlagsCan't name anything; describes something passive ("I watch a lot of YouTube"); no evidence of structured improvement.

No answer or waits for manager
2
Works harder, no specificity

Diagnoses a specific bottleneck
4
Diagnoses + targets the weakest lever
5
Systems thinker — breaks down the full funnel, finds the constraint, A/B tests a fix
✅ Green FlagsDiagnoses which part of the funnel is underperforming (connect rate? show rate? ICP targeting?); targets one variable at a time; seeks coaching on specific weaknesses.
🚩 Red Flags"I'd just make more calls"; has no diagnostic process; waits for manager to identify the issue; treats improvement as effort, not optimization.
🎯

Panics or hangs up
2
Awkward response, drops the thread

Graceful, plants a seed for renewal
4
Curious, digs in, offers value anyway

🚩 Red Flags"Okay, I'll take you off my list"; immediately bashes the competitor; has no long-play strategy; treats a locked prospect as a dead lead.

Clear 30-day plan, multiple inputs
4
Customer interviews, call analysis, first outreach attempt by day 5
5
Systematic ramp: customer calls, win/loss review, ICP doc, mock outreach before day 7
✅ Green FlagsPrioritizes talking to customers first (not just product training); reviews recorded calls and win/loss data; builds a personal ICP cheat sheet; starts practice outreach by end of week 1.
🚩 Red FlagsPassive ramp mindset; waits for manager to assign tasks; doesn't mention talking to customers; focuses only on product knowledge without prospect-facing context.

🎭 Bonus: The 5-Minute Cold Call Role-Play

Run this after questions 1–25. It's the single highest-signal activity in an SDR interview and should happen in every first-round screen.

1Set the scene: "I'm a VP of Sales at a 60-person SaaS company. You're calling me cold. Go ahead."
2Give them 2 interruptions: "I'm really busy" and "What does this actually do?"
3Score on: Hook quality (1–5), Objection handling (1–5), Close attempt (1–5)
4After: Ask "What would you do differently?" — this reveals coachability in real-time.

Frequently Asked Questions

What is the 5-factor SDR hiring model?

The 5-factor model evaluates SDR candidates on Communication (30%), Outbound Experience (25%), Coachability (20%), Trajectory (15%), and Domain Fit (10%). The weights reflect predictive power for on-the-job performance in outbound SDR roles. Communication and Outbound together account for 55% because they're the hardest to teach.

How should I score SDR interview answers?

Use the 1–5 scale in each question's rubric. Score 3 as "meets bar" — don't inflate scores. After all 25 questions, multiply each factor score by its weight and sum for a weighted total. A score above 4.0 is a strong hire signal; below 3.0 is typically a pass.

How long should an SDR interview take?

This full kit runs 50–60 minutes: 5-minute intro, 35–40 minutes on questions (you won't ask all 25 — pick 2–3 per factor), 5-minute role-play, and 10 minutes for candidate questions. For a phone screen, cover Communication and Outbound questions only (~20 minutes).

Should I do the role-play in a first interview?

Yes. The cold call role-play is the fastest filter in SDR hiring. Do it early — in the first 30-minute screen. You'll immediately see communication quality, confidence under pressure, and ability to handle objections. Candidates who blank on the role-play rarely perform well in the field.

What's a good weighted score cutoff for hiring?

4.0+ is a strong hire in most markets. 3.5–3.9 warrants a second interview or reference check to validate coachability. Below 3.0 is a pass for most companies. For seed-stage companies with limited budget for managers to coach heavily, raise the bar to 4.0+ on Coachability specifically.
