Sales Development Representative Job Description

A Sales Development Representative (SDR) is the engine of top-of-funnel growth. They prospect, qualify, and hand off leads so that closers can focus on deals rather than discovery. A great SDR combines relentless curiosity with thick skin — they research prospects deeply, craft personalised outreach, handle objections confidently, and keep CRM data immaculate. The right hire measurably shortens sales cycles and raises average deal quality from day one.

What to look for in a great SDR

Beyond quota numbers, look for evidence of process. The best SDRs can walk you through exactly how they research an account, why they chose a particular opening line, and what they changed after a sequence underperformed. Coachability matters more than polish — someone who absorbs feedback and iterates quickly will outpace a natural talker who never evolves. Also probe for grit: SDR roles involve a lot of rejection, so ask for a specific story about a rough patch and how they pushed through it.

Where to source SDR candidates

University sales programmes, business development bootcamps, and internal promotions from customer support are reliable pipelines. Recruiting from adjacent roles — recruitment consultants, account managers at SaaS vendors, inside sales reps — can yield candidates who already understand B2B buying cycles. Referrals from your existing sales team carry strong signal because salespeople rarely recommend someone they would not want to work alongside. LinkedIn sourcing with targeted boolean searches on 'BDR', 'SDR', or 'inside sales' in your target city is a cost-effective starting point.

Interview questions to ask an SDR

Ask them to sell you something on the spot — it does not matter what, you are evaluating composure and structure. Follow up with 'Walk me through your current prospecting sequence and why you built it that way.' Ask about a deal they lost at the qualification stage and what they learned. Finally, give them a realistic objection ('We already have a vendor for this') and watch how they handle it — do they fold, bulldoze, or genuinely explore? The last question reveals more about future performance than a CV ever will.

Screening a Sales Development Representative quickly

The fastest signal in SDR screening is a short live role-play. Give a candidate a one-line company description and ask them to leave a cold voicemail or open a call, then listen for tone, curiosity, and whether they lead with a reason to care rather than a pitch. Follow with a written cold-email test on the spot, which reveals research habits, brevity, and personalisation instantly. Coachability matters more than polish at this level, so change one thing about their approach and see if they adapt in real time. Grit shows up in how they talk about rejection, so ask about their worst week and whether they still hit activity the next day.

Onboarding a new Sales Development Representative

New SDRs ramp fastest when the first two weeks are about your product and buyer, not just cold-calling technique. Have them shadow discovery calls, learn the top three objections and the honest answers, and understand what a qualified opportunity actually looks like for your Account Executives. Set activity expectations early but pair them with quality checks, since a flood of poorly researched touches damages the brand. Give them a warm list first to build confidence before fully cold territory. Weekly call reviews with specific, recorded feedback accelerate improvement far more than a monthly number. A clear, written definition of a handoff prevents friction with the AE team from day one.

FAQ

Hiring a Sales Development Representative — FAQs

What does a Sales Development Representative do? +
An SDR focuses exclusively on the top of the sales funnel. They identify potential customers, conduct outbound outreach via calls and emails, qualify prospects against defined criteria, and schedule discovery calls or demos for senior salespeople. The role is metric-driven, with success measured by qualified meetings booked and pipeline generated rather than closed revenue.
What skills does an SDR need? +
Core skills include confident cold calling, persuasive written communication, CRM proficiency, objection handling, and the ability to research accounts quickly. Soft skills like resilience, active listening, and time management are equally important because the role involves high rejection rates and requires disciplined daily activity management.
How much does an SDR earn? +
SDR compensation typically combines a base salary with a variable component tied to meetings booked or pipeline created. Total earnings vary widely by industry, company stage, and geography — entry-level roles in smaller markets pay less than positions at high-growth tech firms in major cities. It is best to benchmark against current local salary surveys for the most accurate range.
How long does it take to hire a Sales Development Representative? +
SDR roles usually fill faster than most sales positions because the talent pool is larger and the role is often entry-level. With an active pipeline, expect roughly two to four weeks from posting to offer, since the loop is short: a screen, a role-play, and a manager interview. The bottleneck is rarely finding applicants but filtering for coachability and resilience, so build in a practical exercise. Hiring several at once for a cohort start can shorten the effective time per hire and make onboarding more efficient.
What is the difference between a junior and senior SDR? +
A junior SDR focuses on volume and following the playbook: sequences, cadences, and hitting activity targets while learning the product. A senior or lead SDR handles more complex accounts, personalises outreach more sharply, mentors newer reps, and often books meetings with harder-to-reach buyers. Seniors also feed insights back into messaging and target lists. Many senior SDRs are being groomed for an Account Executive seat, so their conversations lean more consultative and their qualification is tighter than a newcomer's.
