A sample answer to question 1

Why do you want to be a Sales Development Representative?

I've always enjoyed conversations that go somewhere, and the SDR role is essentially about having lots of them and working out quickly whether you can help someone. I like that it's measurable. You know at the end of each day how many leads you've worked, how many conversations you've had and what turned into a meeting, so you can see yourself improving. In my current customer service job I handle around 50 calls a day and regularly identify upgrade opportunities, which I pass to the sales team, and I've realised I'd rather be on the side that drives that conversation. I'm also attracted to the learning. SDRs get a front-row view of what customers care about and how the sales process works, which I see as the best grounding for a sales career. I'd like to grow into an account executive role eventually, but I'm keen to master this first.

Common mistake to avoid: Seeing it only as a stepping stone; No evidence of handling volume
