Direct answer
To hire a Marketing Director effectively, first define the commercial problem the person needs to solve, what success should look like and what level of leadership the business genuinely needs.
Then agree the salary, decision-makers, assessment criteria and interview process before approaching the market.
1. Start with the problem
Why does this hire exist?
Maybe growth has stalled.
Maybe marketing has become a collection of disconnected channels.
Maybe the founder still owns half the marketing decisions.
Maybe there's a strong team with nobody experienced enough to lead it.
Start there.
2. Work out what kind of Marketing Director you need
Builder or optimiser?
Brand-heavy or performance-led?
B2B or consumer?
Hands-on or leading a sizeable team?
Transformation or steady growth?
There isn't one universal "great Marketing Director".
There's a great Marketing Director for this business, at this stage, with this problem.
3. Get realistic about salary
Don't build the perfect candidate in your head and only afterwards discover the market values that person very differently.
Sense-check it early.
4. Decide how you'll judge people
What evidence would convince you this person can do the job?
Agree it before interviewing.
Otherwise it's remarkably easy to hire the person everybody "liked".
5. Move
You don't need to make a reckless decision.
You do need to respect that good people have options.
Decide who's involved, how many stages are genuinely necessary and when decisions will be made before the first interview.
