TL;DR
Practical playbook for hiring Junior SDRs: role expectations, core skills, sourcing channels, structured screening, interview questions, rejection reasons, rubric, closing tactics, red flags, and onboarding steps.
Role Overview
A Junior Sales Development Representative (SDR) is an early-career, outbound-focused sales rep whose primary responsibility is to generate qualified meetings and pipeline for Account Executives. They prospect via cold calls, email sequences, and social outreach, research target accounts, qualify leads to a defined framework, and maintain accurate CRM records. This is a high-activity, measurable role ideal for candidates who are coachable, persistent, and detail-oriented.
What That Looks Like In Practice
A typical day includes building prospect lists, sending personalized outreach, making discovery calls, updating CRM fields and activity, and preparing handoffs for AEs. Success is measured by activity metrics (dials, emails, LinkedIn touches), meetings booked, conversion rates, and data hygiene. Early wins are scheduling the first handful of qualified meetings and demonstrating consistent follow-up that turns into pipeline.
Core Skills
These are the hard skills and tactical abilities you should require or train for in a Junior SDR.
- Prospecting & Lead Generation Ability to research companies and contacts, build lists, and rapidly iterate messaging for target personas.
- Outbound Outreach (Calls, Email, Social) Comfort making cold calls, writing short, personalized emails, and using LinkedIn for outreach and follow-up.
- CRM & Tech Stack Familiarity with CRM tools (Salesforce, HubSpot) and cadence platforms (SalesLoft, Outreach) or demonstrated ability to learn them quickly.
- Basic Qualification Frameworks Understanding of simple qualification approaches (e.g., BANT, MEDDIC-lite, CHAMP) and ability to qualify to an agreed handoff standard.
- Activity Reporting & Data Hygiene Consistent logging of activities, accurate lead/contact data, and comfort pulling simple reports on outreach and pipeline metrics.
Expect new hires to ramp into these skills over 30–90 days; prioritize coachability and baseline competence when hiring.
Soft Skills
Soft skills often predict success more than early technical skill for junior SDRs. Focus on traits you can coach, not just experience.
- Coachability Openness to feedback, quickly implementing coaching, and iterating on messaging and process.
- Resilience and Persistence Ability to handle frequent rejection and keep pursuing target accounts with a structured follow-up approach.
- Communication Clear, concise verbal and written communication tailored to different buyer personas.
- Time Management & Organization Prioritizes high-impact tasks, manages multi-touch cadences, and keeps CRM clean.
- Curiosity & Problem-Solving Asks good questions, researches prospects, and adapts outreach based on buyer signals.
Probe for examples of these behaviors in interviews and reference checks.
Job Description Do's and Don'ts
A clear job description attracts the right candidates and reduces mismatch. Be explicit about what’s required versus what’s preferred.
| Do | Don't |
|---|---|
| List core responsibilities, measurable KPIs (meetings/week, activity targets), and the ramp timeline | Use vague phrases like 'must crush quota' without defining timeline or support |
| Specify non-negotiables (e.g., reliable internet, time zone or office requirement) and what coaching looks like | Pad the JD with lengthy, irrelevant requirements (10+ years experience, senior-level skills) |
| Be clear about compensation structure (base + OTE), career path, and evaluation cadence | Hide commission structure or make promises that sound unrealistic for a junior role |
Keep the JD concise, outcome-focused, and honest about ramp expectations and compensation.
Sourcing Strategy
Junior SDRs can be found in many places — use a multi-channel approach and prioritize volume plus quality.
- LinkedIn Boolean Searches Target titles like 'Sales Development Representative', 'Business Development Rep', 'Inside Sales', and early-stage titles in relevant industries. Filter by activity, recent role changes, and location.
- University & Bootcamp Programs Recruit from recent graduates, sales bootcamps (e.g., SaaS sales academies), and business programs that emphasize communication and sales skills.
- Employee Referrals Offer a structured referral bonus and brief the team on the candidate profile—referrals often yield culturally aligned, motivated hires.
- Sales Communities & Events Source from meetups, local sales chapters, or virtual communities (e.g., Sales Hacker, regional Slack communities) where early-career reps are active.
- Intern to Full-Time Conversions Convert high-performing interns into Junior SDR roles with a structured handoff and ramp plan.
Track source-to-hire conversion rates and double down on channels that give consistent, coachable candidates.
Screening Process
A structured screening process reduces bias and speeds time-to-hire. Keep each stage aligned to a clear decision gate and timebox conversations.
- Resume & Application Screen Confirm relevant signals: outbound or sales-related experience (part-time, internships), measurable achievements, and basic tech familiarity.
- Recruiter Phone Screen (15–20 minutes) Assess motivation, communication clarity, availability, compensation expectations, and basic fit. Ask about sales-related activities and why they want an SDR role.
- Skills Assessment / Take-Home Task Short assignment (e.g., write a 3-email outbound sequence for a provided persona or a 5-minute recorded cold call) to evaluate written messaging and approach.
- Hiring Manager Interview (30–45 minutes) Behavioral questions, real-world scenarios, and a live role-play or discovery call simulation to test qualification and objection handling.
- Final Panel / Cultural Fit Interview Brief session with AE/manager/peer to evaluate handoff expectations, team dynamics, and cultural alignment.
- Reference Check & Offer Call one or two former managers or mentors to verify coachability, persistence, and activity orientation before extending an offer.
Communicate timelines to candidates and use standardized questions and rubrics at each stage.
Top Interview Questions
Q: Why do you want to be an SDR and where do you see yourself in 1–2 years?
A: Look for answers that show realistic career intent (e.g., want to learn sales process, build pipeline skills, move into AE or customer success). Candidates should show motivation for an early-career sales role rather than short-term stopgap reasons.
Q: Walk me through how you would research and reach out to a new prospect in our target market.
A: Strong candidates describe steps: research company pain points, identify the right persona, craft a personalized opening that ties to value, define call-to-action, and plan follow-ups across channels.
Q: Tell me about a time you dealt with rejection or a setback. How did you respond?
A: Effective answers show resilience: they tried alternate approaches, learned from feedback, and adjusted cadence or messaging rather than giving up.
Q: Give an example of a time you improved a process or used data to make a decision.
A: Candidates should demonstrate basic analytical thinking: tracked outcomes, noticed patterns, and iterated to improve conversion or efficiency.
Q: Role-play: You have 6 minutes to qualify a prospect. Start the call.
A: Listen for structure: quick rapport, purpose statement, targeted discovery questions, qualification against your criteria, and a clear next step (meeting or demo).
Top Rejection Reasons
Deciding rejection criteria ahead of interviewing helps you screen out candidates who will struggle to meet the role's demands. Use these reasons to make conscious cutoffs during screening.
- Poor Coachability Candidate dismisses feedback, cannot describe how they’ve applied coaching, or resists process — hard to remediate in a junior role.
- Weak Communication Mumbled answers, inability to convey a simple outreach plan, or poor written communication on the take-home task.
- Lack of Consistent Activity History No evidence of sustained effort (sales, outreach, or other high-volume roles) or inability to describe how they manage follow-ups.
- Dishonesty or Inflated Metrics Vague or unverifiable claims about results, or evasive answers about prior performance.
- Misaligned Motivation Candidate is only looking for a short-term role, has unrealistic expectations about compensation or ramp speed, or seeks immediate senior titles.
Be specific about which red lines are deal-breakers vs. remediable concerns you can coach.

Closing & Selling The Role
Junior candidates care about ramp, learning, compensation clarity, and career progression. Use these talking points to close the best hires.
- Clear Ramp Plan Describe the 30/60/90-day milestones, expected activities, coaching cadence, and what success looks like at each stage.
- Compensation & OTE Explained Be explicit about base, commission structure, near-term earning potential, and realistic timelines to reach OTE.
- Career Path Show examples of SDRs who moved into AE, Customer Success, or Operations roles and the typical timeline for promotion.
- Training & Support Outline onboarding content, role-playing frequency, CRM training, and manager check-ins.
- Culture & Wins Share team rituals, recent wins, and how SDRs are celebrated to help candidates visualize day-to-day life.
Be transparent about timelines, expectations, and compensation to build trust and reduce early attrition.
Red Flags
Watch for early warnings that indicate likely failure in the role. These are distinct from fixable skill gaps.
- Vague Achievements Without Metrics Claims like 'I exceeded expectations' with no numbers or context make it hard to evaluate impact.
- Entitlement or Bad Attitude Complaints about previous managers, unwillingness to do high-volume outreach, or expecting rapid promotion without evidence.
- No Follow-Up Discipline Candidate cannot describe a cadence or example where follow-up turned a 'no' into a meeting.
- Unreliable or Inconsistent History Frequent unexplained job-hopping, unexplained gaps, or references that are unwilling to speak to performance.
- Dishonesty in Screening Inconsistencies between resume, take-home task, and answers in interviews.
Onboarding Recommendations
Structured onboarding accelerates time-to-first-meeting and reduces early churn. Provide clear daily and weekly expectations.
- Week 1 — Orientation & Foundation Company overview, product fundamentals, buyer personas, CRM setup, and initial tooling training. Introductions to AEs and cross-functional partners.
- Week 2 — Messaging & Role-Play Teach ideal outbound cadences and value propositions. Daily role-plays focused on cold opens, objection handling, and qualifying questions.
- Week 3 — Shadowing & Guided Outreach Shadow experienced SDRs/AEs on calls, then run supervised outreach with manager feedback. Start logging full CRM activity.
- Week 4 — Independent Outreach with Metrics Execute cadences independently, with weekly metric targets (calls, emails, meetings booked). Manager provides daily feedback and coaching.
- 30/60/90 Day Reviews Formal evaluations at 30/60/90 days covering activity, conversion rates, CRM hygiene, coachability, and next steps for growth.
Schedule regular 1:1s and formal checkpoints at 30, 60, and 90 days to review performance and adapt the plan.
