What Does an SDR Actually Do?

If you’ve been searching for graduate sales jobs, you’ve probably seen the letters “SDR” everywhere.

The job descriptions tend to sound straightforward: generate new business, qualify prospects and book meetings.

But what does an SDR actually do?

The reality is broader than spending all day making cold calls. SDRs research companies, speak with decision-makers, handle objections, uncover business problems and create opportunities that can eventually turn into revenue.

For graduates, it’s also one of the most common routes into B2B and technology sales.

Here’s what you need to know before applying.

What is an SDR?

SDR stands for Sales Development Representative.

An SDR normally works at the beginning of the sales process. Their job is to find potential customers, start conversations and establish whether there’s a genuine opportunity for the company to help them.

Imagine you work for a software company selling technology to HR teams. You might research suitable businesses, identify the relevant HR leader, contact them by phone, email or LinkedIn, ask about their challenges and decide whether your product could genuinely help.

If there’s a good fit, you’ll typically book a meeting with an Account Executive (AE), record what you’ve learned in your CRM and hand the opportunity over.

The AE will usually take it forward and try to close the deal.

So, while SDRs aren’t normally responsible for closing business themselves, they’re an important part of creating the opportunities that eventually become revenue.

Is an SDR basically a cold caller?

Cold calling is certainly part of many SDR jobs, but it’s not the whole role.

Modern sales development usually involves several channels. You might call someone in the morning, email them later that week and interact with something they’ve posted on LinkedIn.

Research matters too.

Strong SDRs aren’t simply working through a huge list of names. They’re asking:

  • What does this company do?
  • Why could it need our product?
  • Who is likely to make the decision?
  • What challenges might that person have?
  • Is there a genuine reason to contact them now?

You don’t need to know everything about a prospect. You need enough context to start a relevant conversation.

What happens when somebody answers?

This is where sales gets interesting.

Your goal isn’t to launch immediately into a memorised pitch. You need to understand the person you’re speaking to.

What are they doing currently? What’s causing problems? Is solving that problem actually a priority? Who else might be involved in the decision?

Good SDRs learn to listen rather than simply waiting for their opportunity to speak.

For graduates, this can be a steep learning curve. Speaking to a Sales Director or CEO might initially feel intimidating. A few months later, you could be having those conversations every day.

That’s how commercial confidence develops.

What are SDRs measured on?

Sales development is target-driven.

Exactly how you’re measured depends on the company, but common SDR metrics include:

  • Calls and outreach activity
  • Conversations with prospects
  • Meetings booked
  • Qualified opportunities created
  • Pipeline generated
  • Conversion rates
  • Monthly or quarterly target attainment

That level of measurement doesn’t suit everyone. The benefit is that you usually know where you stand.

You can see whether you’re improving and identify where you’re struggling. For an ambitious graduate, that creates a clear relationship between performance, development, earnings and progression.

What skills do you develop as an SDR?

A good SDR role can teach you a surprising amount about how businesses operate.

You’ll learn to communicate with senior professionals, ask better questions, explain value clearly and deal with rejection.

Some prospects won’t answer. Others will say they’re busy or not interested before you’ve finished your first sentence.

Successful SDRs don’t treat every “no” as a personal failure. Instead, they become curious about their performance.

Why did one opening create a conversation while another didn’t? Which prospects are responding? Which questions get people talking?

That mindset can make a big difference.

How is AI changing the SDR role?

AI is increasingly helping salespeople with research, prospect prioritisation, outreach and administrative tasks.

For new SDRs, that doesn’t make communication skills less important. Arguably, it makes them more important.

If every salesperson can use technology to research prospects and produce an email quickly, the ability to have a useful human conversation becomes more valuable.

The strongest new SDRs will learn to use AI to remove repetitive work without relying on it to do their thinking for them.

What Does an SDR Actually Do?

“One thing people often misunderstand about being an SDR is that success isn’t just about how many calls you make. Activity matters, but the biggest improvement comes when you start thinking about why you’re contacting someone and what might actually make them want to have a conversation. When I first started, speaking to senior decision-makers could feel daunting, but you quickly learn that confidence comes from preparation, practice and having genuine curiosity about their business. The best SDRs are always looking at what worked, what didn’t and what they can change next time. If you’re coachable, resilient and willing to keep learning, you can develop incredibly quickly in the role.”

– Dan Abel, Senior Sales Development Representative

Is an SDR role right for you?

You don’t need to be the loudest person in the room, and you don’t need previous sales experience.

But you probably need to be comfortable with targets, feedback and rejection.

Curiosity, resilience, coachability, communication, organisation, competitiveness and a willingness to learn can all help you succeed.

If that sounds like you, an SDR position can provide a strong introduction to a commercial career.

Where can an SDR career take you?

A common progression is SDR to Account Executive. As an AE, you’ll normally take more responsibility for running sales meetings, progressing opportunities, negotiating and closing deals.

But that’s not the only route.

SDRs can eventually move into sales leadership, account management, partnerships, customer success and other commercial roles.

Your first SDR job therefore isn’t just about your starting salary or commission structure. Look closely at the training, manager, product, culture and progression opportunities too.

At This Is Prime, we see how much the right first sales environment can influence someone’s career. Understanding what an SDR actually does is the first step. The next is finding a company where you’ll be properly trained, challenged and given the opportunity to progress.
