A sample answer to question 1

What does growth marketing mean to you, and how does it differ from traditional marketing?

To me, growth marketing is a systematic and experimental approach to growing a business across the whole customer journey, not just acquisition. Traditional marketing often focuses on awareness and campaigns with a planned start and end. Growth marketing treats acquisition, activation, retention, referral and revenue as one connected system, and constantly tests ideas to find what moves the metrics that matter. In practice, that means working closely with product, engineering, data and customer teams, running a steady flow of experiments, and being willing to stop things that don't work. As a growth marketing manager, I'd set growth targets, prioritise opportunities, manage channel owners or specialists, and report on what we've learned as well as what we've achieved. I'm drawn to the pace and accountability, because you quickly see the effect of your decisions. The qualities that matter are analytical thinking, creativity, comfort with ambiguity and the resilience to learn from experiments that fail.

Common mistake to avoid: Describing it as just paid acquisition; ignoring retention and product
