An SDR role is brutal. 100+ dials a day. Constant rejection. A success rate measured in single-digit percentages. The people who thrive in this role are wired differently — and finding them isn't obvious from a resume.
Most SDR hiring processes optimize for the wrong things: polished interview presence, fancy schools, previous tech experience. None of these predict whether someone can handle getting hung up on 40 times a day and still pick up the phone with energy on dial 41.
This is a complete SDR hiring system. It covers what to look for, where to find candidates, how to run the process, and how to hand off to onboarding successfully.
Part 1: Define the Profile
Before you source candidates, get clear on what actually matters for SDR success at your company. Not generic "communication skills" — specific, testable traits.
The Five Things That Actually Predict SDR Success
1. Rejection resilience SDRs face more rejection per hour than almost any other job. A rep who gets emotionally rattled by "not interested" will burn out in months. Look for evidence of handling adversity: competitive sports, cold calling in previous roles, any job where failure was frequent and visible.
2. Coachability The best SDRs aren't born great — they improve quickly. They take feedback, implement it immediately, and don't get defensive. Test this in the interview: give direct feedback on a role-play and see how they respond.
3. Curiosity and energy SDRs who ask questions about your product, market, and buyers are more likely to engage prospects effectively. Energy matters because phone presence matters — a monotone rep loses prospects in the first 10 seconds.
4. Pattern recognition speed Top SDRs learn which messaging works on which persona within weeks. They adjust their approach without being told. You can't directly test this in an interview, but you can look for evidence: "I noticed my open rates were higher when..." or "I tried a different approach for CFOs because..."
5. Execution discipline SDR success is partly a volume game. Reps who can maintain consistent activity — 80+ dials daily — outperform inconsistent performers with better skills. Ask about how they structure their time and handle repetitive work.
What Doesn't Predict SDR Success
- Previous SDR experience — Useful for faster ramp, but not predictive of top performance. Many successful SDRs come from unrelated fields.
- Degree prestige — No correlation with sales performance. Skip this filter entirely.
- Interview polish — Articulate interviewers aren't necessarily great on the phone with hostile prospects. The interview tests interview skill, not SDR skill.
Your Ideal Candidate Profile
Write this down before you start sourcing. Example:
SDR Ideal Profile:
- Can give specific examples of handling rejection or adversity
- Demonstrates curiosity about our product/market during interviews
- Maintains energy even in role-play under pressure
- Takes feedback and adjusts immediately in live conversation
- Has held a job requiring consistent daily output (service industry, retail, inside sales, etc.)
- Geography: [your location or remote-eligible]
- Experience: 0–3 years (we'll train, prioritize traits over experience)
Part 2: Sourcing
SDR sourcing is volume-dependent. You'll screen a lot of people to find a few good ones. Cast a wide net, then filter ruthlessly.
Where to Find SDR Candidates
LinkedIn (outbound):
- Search for recent grads with sales-adjacent experience
- Target former retail managers, hospitality workers, customer success reps
- Message directly with a clear pitch about the role and company
Job boards (inbound):
- LinkedIn Jobs, Indeed, Glassdoor
- Write a realistic job description (not "rockstar wanted") — attracts self-aware candidates
- Be specific about compensation: "$55K base + $15K OTE" beats "competitive salary"
Employee referrals:
- Your current SDRs know people. Offer a referral bonus ($1K–2K is standard).
- Referrals typically have higher quality and faster ramp
Bootcamps and training programs:
- Vendition, Aspireship, SV Academy produce sales-trained candidates
- They've already filtered for commitment to a sales career
Unconventional pools:
- Former teachers (high communication skills, discipline)
- Former athletes (competitive, resilient)
- Service industry veterans (customer-facing, high-pressure)
- Military veterans (discipline, execution under stress)
Sourcing Volume Math
To hire 2 SDRs, expect to:
- Review ~100 resumes/applications
- Phone screen ~30 candidates
- Advance ~10 to assessment
- Interview ~5 finalists
- Make 2–3 offers
If you need SDRs fast, backsolve the pipeline: to hire 2 in 4 weeks, you need to source 100+ candidates in weeks 1–2.
Part 3: The Hiring Process
A good SDR hiring process is fast (2 weeks from application to offer), efficient (minimal time per candidate until you have signal), and skill-based (test selling ability, not just interview ability).
Stage 1: Resume Screen (2 min/candidate)
Not a gate — a light filter. Look for:
- Evidence of high-activity roles (sales, service, fundraising)
- Career progression (promoted, took on more responsibility)
- Anything that suggests rejection resilience
Auto-advance: Career changers, non-obvious backgrounds — don't filter them out prematurely.
Auto-reject: Obvious mismatches (looking for different role/seniority, geographic mismatch), sloppy applications (wrong company name, generic cover letter).
Stage 2: Phone Screen (15 min)
Quick call to validate basics and assess energy/communication.
Questions:
- Why sales? Why SDR? (Looking for genuine interest, not "need a job")
- Walk me through your typical day in your last role. (Looking for structure, execution)
- Tell me about a time you faced a lot of rejection. How did you handle it? (Looking for resilience, specifics)
- What do you know about [your company]? (Looking for preparation)
Evaluator checklist:
- Clear, energetic communication
- Specific answers (not vague generalities)
- Did research on the company
- Shows genuine interest in sales
Advance if: 3+ boxes checked + gut says "might be good."
Stage 3: Assessment (20 min, asynchronous)
This is where you get real signal. Send every candidate who passes the phone screen an assessment — a sales simulation that tests their ability to handle a realistic SDR conversation.
What the assessment should include:
- Cold call scenario (opening, handling initial resistance)
- Objection handling (2–3 common objections)
- Closing for a next step (booking a meeting)
What you're scoring:
- Can they hold a conversation under pressure?
- Do they listen or just talk?
- Can they recover from rejection without losing composure?
- Do they close for a next step?

Advance if: Score meets your threshold (we recommend 65+ for SDR candidates).
Stage 4: Hiring Manager Interview (30–45 min)
For candidates who pass the assessment, now you do a real interview. But you're not starting from scratch — you have data.
Structure:
- 10 min: Review their assessment results together. Ask about their choices.
- 15 min: Live role-play. Give them a scenario, play the prospect.
- 10 min: Behavioral questions (coachability, motivation)
- 5 min: Questions about the role
Role-play feedback test: After the role-play, give direct feedback: "That opener didn't land for me. Here's why. Try it again differently."
Watch their reaction. A coachable candidate says "Okay, let me try this..." A defensive candidate says "Well, I thought it was fine because..."
This 30-second moment tells you more than any behavioral question.
Interview scorecard:
| Dimension | Score (1–5) |
|---|---|
| Assessment performance | |
| Live role-play performance | |
| Coachability (response to feedback) | |
| Energy and presence | |
| Motivation for the role |
Stage 5: Final Round / Team Fit (30 min)
If you're hiring multiple SDRs, have finalists meet the team. If it's a single hire, this can be a call with a peer SDR and/or the AE they'll be booking meetings for.
Purpose: Confirm team fit, give the candidate a realistic view of the role, catch anything weird.
Not purpose: Relitigate skills. You already have assessment and role-play data. Trust it.
Stage 6: Offer + Close
SDR candidates are often interviewing at multiple companies. Move fast.
Timeline: Make offer within 48 hours of final round. Give 3–5 days to decide.
Sell the role:
- Clear path to AE (if that's your model)
- Strong onboarding / training
- Realistic OTE and how others hit it
- Team culture (share specific examples)
Part 4: The SDR Scorecard
Use this scorecard throughout the process:
| Criterion | Weight | Phone Screen | Assessment | Interview | Final Score |
|---|---|---|---|---|---|
| Rejection resilience | 25% | ||||
| Coachability | 25% | ||||
| Communication / Energy | 20% | ||||
| Motivation for SDR role | 15% | ||||
| Execution discipline | 15% |
Hire if: Weighted average > 3.5 and no dimension below 2.5.
Part 5: Onboarding Handoff
Hiring is not complete when the offer is signed. A smooth handoff to onboarding reduces early turnover and accelerates ramp.
Before day 1:
- Send assessment results to the SDR manager
- Highlight strengths (lean into these in coaching) and gaps (prioritize in onboarding)
- Share interview notes on coachability, motivation, any flags
Day 1:
- Manager 1:1 to set expectations, review 30-day milestones
- Connect to the SDR onboarding checklist
- First practice call within 72 hours
Week 1:
- Daily check-ins with manager
- First call block by day 4–5
- Manager listens to early calls, provides immediate feedback
The assessment-onboarding bridge: The assessment already identified skill gaps. Use that data to prioritize onboarding focus. A candidate who scored 72 on objection handling but 55 on closing should drill closing technique, not objection handling.
Common SDR Hiring Mistakes
Mistake 1: Hiring for polish instead of grit. The candidate who sounds great in the interview might crumble on the phones. The awkward candidate who's hungry and resilient might become your top performer. Test for selling, not interviewing.
Mistake 2: Skipping assessment. Interviews are conversations about sales. Assessments are actual sales. You wouldn't hire a developer without seeing code. Don't hire an SDR without seeing them sell.
Mistake 3: Too many rounds. SDR candidates have options. If your process takes 4 weeks and 5 rounds, you'll lose good candidates to companies that move faster. 2 weeks, 3–4 touchpoints, done.
Mistake 4: Ignoring coachability. An SDR who can't take feedback will plateau fast. The feedback test in the interview (live role-play → feedback → try again) is mandatory.
Mistake 5: No clear profile. If you're evaluating "communication skills" and "drive" with no specifics, you're making gut decisions. Write down the profile before you start.
