Brand Marketing Growth interview prep.

Behavioural questions to expect

1. Walk me through your CV.
2. Tell me about a programme or brand where you owned a measurable growth outcome.
3. Why CPG growth — vs pure DTC, performance agency, traditional brand management, or tech growth?
4. Why this motion — DTC-led vs retail-led vs true omnichannel?
5. Why the firm?
6. What is your read on our brand portfolio, DTC footprint, and digital + omnichannel maturity?
7. How would you describe our channel mix, retailer-media exposure, and e-commerce trajectory?
8. Our DTC sub-brand's blended CAC has climbed 40% in two quarters while retail share is flat. Walk me through the diagnosis and the first three moves.

Technical concepts to master

• Digital growth + DTC + first-party data

  Blended MER + new-customer ROAS · CAC payback (contribution-margin basis) · Retention curve + repeat-purchase economics · First-party-data architecture + identity · Lifecycle + CRM (email + SMS + onsite + push)

• Retailer media + e-commerce + omnichannel

  Retailer media networks (RMN) — onsite + offsite + in-store · Digital shelf + share of voice + content · Omnichannel + JBP integration · Hard discount + private label + pure-play DTC threats · Retailer clean rooms + audience activation

• Brand P&L + 4Ps in growth context

  Brand P&L (NSV -> gross margin -> A&P -> contribution) · Share = distribution * velocity (and how growth changes it) · Price-pack architecture + price-gap discipline · Trade promotion + ROI (gross-to-net discipline) · Innovation pipeline + DTC-as-test-bed

• Measurement + MMM + incrementality

  MMM (media mix modelling) as macro truth · Incrementality testing (geo + matched-market + holdout) · Multi-touch attribution post-ATT · Clean rooms + privacy-safe measurement · Brand-health tracking + equity measurement

Practical drills

• Your DTC sub-brand: blended CAC went from $32 (2Q ago) to $38 (LQ) to $46 (TQ), +44% over 6 months. Marketing spend $1.2M / quarter steady. New customers: 37.5K -> 31.6K -> 26.1K. AOV $54 (flat); contribution margin 35% (flat); second-purchase rate 22% (was 28%). Channel mix shift: paid social 55% -> 70% of spend; web search 20% -> 18%; email + lifecycle 10% -> 5%; influencer 15% -> 7%. Walk through the diagnosis + first three moves.
• the firm wants to build a V1 retailer-media-network programme across the top 3 retail partners for a power brand + a growth brand. Walk through how you would design it — channel mix per retailer, brand prioritisation, sales + JBP alignment, measurement, cadence.
• Your MMM (refreshed last quarter) says paid social is at 0.8x marginal ROAS (you've reported 2.5x via platform). Web search marginal ROAS 1.4x. Linear TV 1.1x. RMN onsite 1.8x. Influencer 1.6x (modelled with regional variance). Email + lifecycle 4.2x. Total marketing spend $40M annual: paid social 40%, web search 15%, linear 20%, RMN 10%, influencer 8%, lifecycle 7%. Walk through how you interpret the MMM + propose a 12-month rebalance.

Smart-question anchors

• Portfolio + DTC footprint — which brands have DTC, which are acquired, how digital revenue is disclosed
• Retailer media network maturity — in-house vs agency, top RMN partners, measurement approach
• First-party data + loyalty programme — list size, CDP investment, identity + governance posture
• Measurement infrastructure — MMM provider, incrementality cadence, multi-touch + clean-room maturity
• E-commerce + omnichannel posture — digital shelf maturity, retailer e-com partnerships, JBP integration
