Senior Marketing — Marketing interview questions

How do you know a channel actually caused the sales it is credited with?

By turning it off, or holding out a region, and seeing whether total sales move — attribution reports cannot answer this because they distribute credit among the touches that happened, not against a world where the channel did not exist. Branded search is the standard example: it converts beautifully and mostly captures demand something else created. Incrementality is expensive to measure and the only honest answer.

A new product, small budget, nobody knows the name. Where do you start?

Where intent already exists, because creating demand costs more than capturing it. That usually means search and the communities where the problem is discussed. Paid is for validating a message quickly, not for growth at that stage. The decision that matters most is narrowing the audience until the message can be specific — broad targeting on a small budget buys nothing.

How do you split spend between brand and performance?

By time horizon and by what is currently limiting you. If performance costs are climbing while volume is flat, the market knows you too little and brand is the constraint. If nobody has heard of you and the funnel converts well, performance still has room. Anyone who gives a fixed ratio without asking about your growth stage is reciting something they read.

How do you tell early that a channel is dying?

Rising cost per acquisition at constant volume, falling conversion at constant traffic, and shrinking reach at constant budget — usually in that order, over weeks rather than days. The mistake is compensating by raising the bid, which hides the trend and buys the same customers more expensively. The response is to test a replacement while the current one still works.

What do you report to a founder, and what do you report to your team?

The founder gets money and time: cost to acquire, payback period, how many customers this month and the trend. The team gets the levers they can move: creative performance, page conversion, the specific test running now. Sending either report to the other audience is how marketing loses credibility — the founder cannot act on click-through rate and the team cannot act on payback period.

Who is the first marketing hire and why?

Usually someone who can write, because content, ads, email and positioning are all writing, and the alternative is buying it badly from an agency. A channel specialist is the wrong first hire because the channel is not decided yet, and you would be locking in the answer before asking the question. Whoever it is has to be comfortable measuring their own work.

Sales says the leads are poor and blames you for the missed target. How do you respond?

By making the definition explicit before arguing about volume: what qualifies a lead, who agreed it, and when it was last reviewed. Then look at the data together — conversion by source, by campaign, by segment — because usually one channel is dragging the average and the rest are fine. The unproductive version of this conversation is defending the total number, which nobody disputes.

What is ABC analysis and how would you use it in marketing?

It splits items into three groups by contribution — A being the small share that produces most of the value. Applied to channels, campaigns or customer segments, it usually shows that a handful account for most of the revenue and the rest consume attention. Its use is deciding what to stop, which is harder than deciding what to start and is where the budget actually comes from.

When is account-based marketing worth doing?

When the deal size justifies treating a single company as a market — few prospects, long cycles, a buying committee. It stops being worth it as soon as the target list grows past what a team can genuinely personalise, at which point it becomes ordinary campaigning with extra cost. It also requires sales to work the same accounts on the same timeline, and without that agreement it produces nothing.

How do you develop positioning?

By naming the alternative you displace, the audience for whom that displacement matters, and the one capability that makes it credible. The competitor is rarely another vendor — most often it is a spreadsheet, an agency or doing nothing. Positioning derived from a feature list ages badly, because features get copied and the reason someone switched does not.

What makes a KPI properly set?

That it is measurable with the data you actually have, owned by someone who can move it, bounded by a period, and hard to hit by doing something harmful. The last is the one that gets skipped: a lead target with no quality constraint reliably produces bad leads, and a traffic target produces traffic. A good KPI names the counter-metric that keeps it honest.
