Interview guide for marketing roles: a full loop with a portfolio review and campaign brief

Marketing candidates are good at presenting their own work, which makes them hard to interview. The loop has to get past the case-study version of each campaign to what the candidate decided, how they measured it, and whether they can do it again on a new brief. This guide gives hiring managers a complete loop for a mid-level marketing manager running campaigns for a B2B or consumer product: five stages, who owns which competency, core questions with what to listen for, a portfolio review and a campaign brief exercise, the scorecard weights, and the debrief decision rule.

First-call questions are in marketing manager phone screen questions. The arithmetic for weighting a marketing scorecard, with a worked marketing example, is in weighted interview scorecard. This page is the loop around both.

The loop at a glance

Total candidate time is about four and a half hours including the 90-minute written plan. Tell candidates the full schedule after the screen, including the time cap on the exercise, so those with less free time are not at a disadvantage.

Stage 1: the screen (30 minutes)

• "Which channels have you run yourself, with roughly what budget, and which did you hand to an agency or colleague?" Listen for: hands-on ownership of at least the channels this role depends on, and honest lines between what they ran and what they oversaw.
• "Who did your work serve: sales, product, the customer directly? How did they judge whether marketing was doing its job?" Listen for: an outcome measure the business cared about, such as qualified pipeline or retention, not only follower counts or open rates.

The screen also settles location, pay and notice, so the hiring manager does not spend scored time on them.

Stage 2: hiring manager interview (45 minutes)

1. "Tell me about the campaign you are proudest of. What was the goal before launch, and how did you measure it?" Listen for: a target set in advance, a metric connected to the business (pipeline, revenue, retention) rather than only reach, and an honest account of attribution limits.
2. "Tell me about a campaign that missed. When did you know, and what did you do?" Listen for: early signals they were watching, a decision to adjust or stop, and what they reported upward.
3. "Tell me about a time you had to cut your budget mid-quarter. What did you cut and why?" Listen for: knowing which channels earned their spend, a reason for each cut, and protecting what worked.

Stage 3: portfolio review (45 minutes)

Ask the candidate to bring two pieces of work they were responsible for: one that worked and one that did not. The peer marketer spends about 20 minutes on each.

• "What was your part, specifically? Who else worked on it?" Listen for: a clear line between what they did and what agencies, designers or colleagues did.
• "Walk me through the timeline. Where did it slip, and how did you recover?" Listen for: project control, dependencies managed, decisions made under deadline.
• "If you ran it again tomorrow, what would you change?" Listen for: a specific change grounded in what they learned, not "more budget".

Candidates may not be able to share numbers from a current employer. Accept ranges or relative changes; the reasoning is what you are scoring.

Stage 4: the campaign brief exercise

Send an invented one-page brief two days before the final interview: a meal-kit company launching a lower-priced plan for students; a quarterly budget figure; two customer segments with short descriptions; one constraint (for example, no paid social because of a past brand issue); and the goal of new subscriptions in eight weeks. Ask for a one-page plan, written in no more than 90 minutes, and say that the cap is the expectation, not a minimum.

The 45-minute live discussion

• 10 minutes: the candidate walks through the plan.
• 15 minutes of probing: "Why this audience first? What would you test in week one? How will you know by week three if it is working?"
• The change at minute 25: "Finance just cut the budget by 40%. What stays?"
• 10 minutes of live writing: hand over 150 words of weak launch copy and ask for a sharper version for one segment. Listen for: a clear message for that audience and cutting before adding.

Listen for: a plan that follows from the goal and the audience, a small set of channels with a reason for each, measurable checkpoints, sensible use of the constraint, and a clear priority under the budget cut. Creative ideas count when they fit the audience and can be tested. The creativity questions add a behavioral check if the role is content- or brand-heavy.

Stage 5: partner interview (30 minutes)

• "Tell me about a time sales said your leads were bad. What happened?" Listen for: looking at the data together, agreeing a definition of a qualified lead, and changing something on both sides. Blaming sales follow-up alone is a weak answer.
• "Tell me about a launch where you and product disagreed on the message." Listen for: customer evidence used to settle it, and a message both sides could defend.

Scorecard competencies and weights

Example weights for a campaign-focused marketing manager. Set yours at intake and lock them.

The scorecard builder checks the weights total 100 and prints the decision rule on the sheet.

The debrief decision rule

1. Scorecards and the candidate's one-page plan are in before the debrief; nobody reads other scores first.
2. Gate: campaign strategy at 3 or above from both people in the exercise.
3. Floor: no 1 on measurement and attribution honesty. A marketer who claims credit they cannot explain will make every future report harder to trust.
4. Weighted total: in this example, 2.8 or higher on the 1–4 scale goes to references.
5. References: include one from sales, product or finance to confirm how the candidate's results were seen outside marketing.

Adjusting for other marketing roles

Common mistakes in marketing loops

• Scoring the deck. Polished slides show design skill or a good template, not campaign judgment. Score the reasoning under questioning.
• Accepting headline numbers. "Grew pipeline 200%" means little without the starting point, the time frame and what else changed.
• A real-company take-home. It tests insider guesses and asks for free work. Use an invented brief.
• Leaving out the partner team. Marketing that sales or product will not work with fails quietly. Include one of them.

Once you have hired, a 30-60-90 day plan for marketing managers sets out the first quarter.
