Suggested Approach

Start by clarifying the scope of the adtech platform (e.g., demand-side, supply-side, or retail media) and the role's focus (e.g., backend, data, or full-stack). Then, structure your answer around core functional areas such as campaign management, targeting, real-time bidding, measurement, and integrations, highlighting scalability and data challenges relevant to Walmart Labs.

Pro tip: Emphasize how Walmart's unique position as a retailer with massive first-party data enables closed-loop attribution and retail media networks, differentiating it from pure adtech players.

1. Clarify Scope and Context

Ask clarifying questions to understand the platform type (e.g., DSP, SSP, DMP, retail media) and the specific role expectations. This shows you can tailor your answer to the interviewer's needs.

2. Identify Core Functional Modules

List the essential components such as campaign management, ad serving, targeting, bidding, measurement, and reporting. Group them logically to demonstrate structured thinking.

3. Highlight Technical Challenges and Scalability

Discuss the need for low-latency bidding, high-throughput data processing, and real-time analytics. Mention technologies like Kafka, Spark, or microservices that address these challenges.

4. Connect to Walmart Labs' Ecosystem

Tie features to Walmart's strengths: first-party data, omnichannel presence, and retail media. Explain how these enable unique ad products like sponsored search and display.

5. Summarize and Invite Follow-up

Concisely recap the key features and express openness to dive deeper into any area. This shows confidence and engagement.

Key Points to Mention

  • Campaign management and ad serving with real-time bidding (RTB) capabilities
  • Audience targeting and segmentation using first-party and third-party data
  • Measurement and attribution, including closed-loop reporting for retail media
  • Scalable data pipelines and low-latency infrastructure for high-volume ad requests
  • Integration with ad exchanges, DSPs, SSPs, and Walmart's internal systems
  • Privacy compliance and identity resolution (e.g., cookie-less targeting, hashed emails)
