Sudden metric drop, no recent deployments. What's the cause?
This tests your ability to debug data discrepancies beyond code, focusing on the analytics pipeline. First, distinguish data loss from misattribution. Then, check processing delays and hidden data sources. A red flag is not segmenting data first.
How would you identify and elevate a team's primary constraint?
This tests your systems thinking beyond local optimization. A great answer follows the 5 Focusing Steps: Identify, Exploit, Subordinate, Elevate, Repeat. A red flag is jumping to 'hire more people' before exploiting the existing constraint and subordinating…
How would you debug a sudden drop in a key metric?
Tests your systematic debugging of complex data systems. First, validate the drop against a source of truth and segment the data. Then, hypothesize causes like misattribution or data loss.
How would you identify and elevate your team's primary constraint?
This tests systems thinking over local optimization. A great answer outlines the 5 steps: identify the constraint (e.g., long queues), exploit it, subordinate other processes, elevate it, and repeat. A red flag is jumping straight to hiring or buying tools.
How do you analyze a major technology trend for product impact?
This tests strategic discernment. A strong answer frames a time-boxed analysis across feasibility, user-value, cost, and risk, separating hype from capability. Red flag: jumping to build or dismiss without structured criteria or user evidence.
How do you attribute signups to Facebook, Google, and blog campaigns?
This tests URL-based campaign attribution and session persistence. A strong answer covers UTM tags, landing page parsing, cookie storage, and writing the source to the user record at signup.
Trade-offs: third-party analytics SDK versus in-house pipeline
This tests strategic build-versus-buy judgment for data infrastructure. Strong answers weigh time-to-market, maintenance burden, data sovereignty, and compliance against core product focus.
How would you implement a software Andon Cord equivalent?
This tests translating Lean stop-the-line into CI/CD culture. Trigger: compile, test, or integration failures. Impact: halt pipeline, block merges, and swarm to fix immediately with collective ownership. Red flag: blaming committers or deferring fixes.
Build vs. Buy: Third-Party Analytics SDK or In-House Pipeline?
This tests your grasp of the time vs. control trade-off. A great answer weighs the speed of buying against the total control of building, focusing on the hidden, long-term maintenance costs of an in-house solution.
How would you implement an Andon Cord for a software team?
Tests your grasp of CI/CD, quality, and team culture. A great answer defines a trigger (broken main build), a technical block (stop merges), and a cultural response (team swarms). A red flag is scheduling the fix or blaming an individual.
Build vs. Buy: Third-Party vs. In-House Analytics
Tests your grasp of the time-vs-control trade-off. A great answer weighs speed vs. customization and total cost of ownership. Advocating for 'build' without considering the massive, ongoing maintenance cost is a major red flag.
How would you implement an Andon Cord for a software team?
Tests your understanding of CI, team ownership, and balancing speed with quality. Define a trigger (broken main build), an action (halt merges/deploys), and a team response (swarming to fix). Red flag: scheduling the fix or blaming an individual.
Instrument a first-full-song activation event
Define 'full song' server-side, emit a typed event with user, song, and context, dedupe the first-time flag.
How would you use telemetry and logs to refine SAM calculation?
Tests bridging telemetry to SAM. A strong answer maps API usage and feature flags to fit, uses performance logs to expose delivery limits, and rebuilds SAM from qualified accounts. Red flag: calling all logs demand without checking constraints.
How do you approach user identity stitching across devices?
Tests cross-channel identity resolution design. Strong answers capture a persistent anonymous ID per device, rekey to a person ID at login via field-based or graph-based stitching, and respect consent.
Three accountabilities in a Scrum Team and their primary focuses
Tests recall of the three Scrum accountabilities. Outline: Product Owner orders the backlog; Developers create an Increment each Sprint; Scrum Master fosters an environment for empiricism. Red flag: Using roles or treating the Scrum Master as a task master.
How do you approach user identity stitching?
This tests your grasp of data architecture for analytics, not just a simple algorithm. A strong answer defines anonymous vs. known IDs, explains the backfilling/rekeying process upon authentication, and notes the need for a central event store.
What are the three Scrum accountabilities and their focus?
Tests recall of Scrum's core team structure and how the roles create a self-managing unit. A good answer names the Product Owner (value), Developers (Increment), and Scrum Master (process) and defines their focus.
How do you approach user identity stitching across devices?
This tests your grasp of event-driven data pipelines and identity management. A strong answer outlines an identifier hierarchy, the "stitch" event (login), and a backend process for retroactively applying a canonical user ID.
What are the three accountabilities in a Scrum Team?
Tests recall of Scrum fundamentals and separation of concerns. Name the three accountabilities (Product Owner, Scrum Master, Developers) and define their focus: PO on value, Developers on delivery, and SM on process. A red flag is adding non-Scrum roles.
