Product Management interview prep.

Behavioural questions to expect

1. Walk me through your CV.
2. Tell me about your most impressive product launch or feature.
3. Tell me about a weakness, a failure, or feedback you've received and worked on.
4. Why payments / fintech product management - and why now?
5. Which product area would you want to own, and why?
6. Why the firm?
7. How would you describe the firm's product and edge in your own words?
8. How does the firm actually make money - and how is that changing?

Technical concepts to master

• Payment ecosystem roles

  Issuer (bank) · Acquirer (merchant bank) · Network (Visa / Mastercard / Amex / Discover) · Processor + gateway

• Auth rate + the payments funnel

  The auth funnel · Network tokens · Smart retries · 3DS / SCA optimisation

• Fraud, chargebacks + disputes

  Fraud vs chargeback vs dispute · Chargeback monitoring + network thresholds · Fraud rules + ML risk scoring · Representment + dispute economics

• PM frameworks + metric design

  RICE prioritization · CIRCLES (or similar) for product design · North Star + OKRs · A/B testing discipline

Practical drills

• A merchant processes $10m / month of card volume through the firm. Blended take rate is 2.6% gross. Interchange averages 1.5%, network assessment 0.13%, fraud cost 0.05%, chargeback cost 0.10%, processor / infra 0.20%. (a) Net take rate. (b) Monthly gross + net revenue from this merchant. (c) If a competitor offers a 2.4% all-in rate, can the firm match and still earn a positive net margin? What's the floor?
• Auth rate on the firm's checkout is stuck at 88%; the team wants 92%. Walk me through how you'd diagnose, pick levers, and design the experiment.
• the firm wants to build a B2B accounts-receivable product for mid-market SaaS companies (selling to enterprise buyers, $5-50m invoices, 30-60 day DSO). Walk me through how you'd design the V1.

Smart-question anchors

• Stack position + segment - where the firm sits (issuer / acquirer / processor / platform), the customer, and where it's leaning
• Product surfaces + roadmap - the headline products, recent launches, what's next, and how PMs influence the roadmap
• Metrics + experimentation - the firm's North Star + key metrics, the experimentation cadence, and how decisions are made
• Regulatory + compliance - the regulatory frame the firm operates under, recent regulatory work, and how PMs partner with comp / risk
• Cross-functional + eng culture - how PMs partner with eng / design / risk / sales; developer-first vs sales-led
