Why they ask: They want to hear whether you operate at strategic level and not just as a senior channel specialist.

2. How would you build a twelve-month digital marketing roadmap for a business you have just joined?

Why they ask: They test strategic planning and how you sequence priorities with limited resources.

3. What is blended marketing efficiency ratio, and how do you use it alongside platform-reported ROAS?

Why they ask: They want to see a disciplined approach to portfolio decisions and experimentation.

6. What would you put on a monthly digital performance report for the board, and what would you leave out?

Why they ask: Reporting upwards needs clarity and commercial focus, so they test how you communicate.

Why they ask: They test how you handle conflicting data and protect budget effectiveness.

8. Tell me about a time you reallocated significant budget between channels. How did you decide and what happened?

A sample answer to question 1

What does a Head of Digital Marketing do, and what will you bring to the role?

A Head of Digital Marketing owns the strategy, performance and capability of all digital channels, which typically include paid search and social, SEO, email and CRM, the website experience, analytics and marketing technology. That means setting goals linked to commercial outcomes, deciding where budget goes, building a team and agency partnerships that can deliver, and making sure that measurement is trustworthy enough to base decisions on. It also means translating digital performance for the board and challenging other directors when digital is not being used well. What I would bring is a blend of channel depth and commercial thinking. I have run paid, organic and lifecycle programmes, so I can tell whether the work is good, and I am comfortable owning a budget and a profit-and-loss target. I also care about people development, because the best results come from a team that is clear on priorities and trusted to take decisions, and from a culture that tests ideas instead of guessing.

Common mistake to avoid: Describing yourself as the best channel operator; ignoring leadership responsibilities
