By maintaining a strong focus on transparency and efficiency, you will help Index Exchange deliver trusted, innovative solutions that empower media owners and partners in the digital advertising ecosystem.

2.1 Stage 1: Application & Resume Review

This initial step is conducted by the Index Exchange recruitment team and centers on evaluating your background for core product management experience, technical acumen (especially in adtech or audience/segmentation data platforms), and demonstrated ability to deliver on product launches. The team will look for evidence of analytical thinking, cross-functional collaboration, and communication skills in your resume and cover letter. To prepare, ensure your materials clearly reflect measurable impact, leadership in product development, and experience with complex technical integrations.

2.2 Stage 2: Recruiter Screen

A dedicated HR representative leads a conversational phone or video interview to discuss your professional journey, motivation for joining Index Exchange, and fit with the company’s values of transparency and innovation. This stage typically lasts 45-60 minutes and also covers logistical details such as your availability, compensation expectations, and work eligibility. Preparation should focus on articulating your passion for programmatic advertising, ability to thrive in a fast-paced environment, and alignment with Index Exchange’s commitment to diversity and inclusion.

2.3 Stage 3: Technical/Case/Skills Round

Led by a senior product leader or program director, this round assesses your product sense, technical depth, and problem-solving skills. Expect scenario-based questions involving adtech platforms, audience segmentation, data-driven decision making, and product strategy. You may be asked to analyze marketplace metrics, evaluate product features, or propose solutions for evolving platform capabilities. Preparation should include reviewing your experience with launching complex products, collaborating with engineering and UX teams, and setting measurable success metrics for product features.

2.4 Stage 4: Behavioral Interview

This stage is designed to evaluate your leadership style, stakeholder management skills, and ability to navigate ambiguity. Interviewers from cross-functional teams (such as commercial, engineering, or customer service) will probe for examples of how you’ve handled challenging situations, balanced competing priorities, and made tough tradeoffs. Be ready to discuss how you build consensus, communicate with diverse groups, and foster an inclusive and collaborative product culture. Preparation involves reflecting on past experiences where you demonstrated resilience, humility, and conviction in decision-making.

2.5 Stage 5: Final/Onsite Round

The final stage typically includes a series of deeper interviews with product, engineering, and executive stakeholders, either virtually or in person. You’ll be expected to present your approach to building scalable product solutions, integrating partner feedback, and driving business outcomes within the adtech ecosystem. This round may involve a case presentation or whiteboard exercise, as well as a discussion of your vision for Index Exchange’s Marketplaces platform.

3.1 Product Strategy & Business Impact

Product Managers at Index Exchange are expected to drive business growth by using data to inform product decisions, evaluate new opportunities, and measure outcomes. You’ll need to show your ability to design experiments, set relevant KPIs, and translate insights into actionable recommendations for cross-functional teams.

3.1.2 How would you analyze how the feature is performing?

3.3.1 How would you find out if an increase in user conversion rates after a new email journey is casual or just part of a wider trend?
Discuss setting up control groups, running statistical tests, and accounting for external factors. Example: “I’d compare conversion rates before and after the change, control for seasonality, and run significance tests.”

3.3.2 Write a query to compute the average time it takes for each user to respond to the previous system message
Explain how you’d use window functions to align events and aggregate response times. Example: “I’d join messages by user, calculate time deltas, and summarize by user ID.”

Describe filtering and aggregation techniques to identify users meeting both criteria. Example: “I’d use conditional aggregation to flag users and filter those who never had a ‘Bored’ event.”

3.3.4 Aggregate trial data by variant, count conversions, and divide by total users per group. Be clear about handling nulls or missing conversion info.
Summarize how to structure the analysis for conversion rates, handle incomplete data, and interpret results. Example: “I’d group by variant, calculate conversion rates, and adjust for missing data.”

3.3.5 How would you ensure a delivered recommendation algorithm stays reliable as business data and preferences change?
