Technical-coding (hard): Provide pseudocode for computing statistical significance and uplift for multiple concurrent A/B experiments with overlapping populations. Inputs: arrays of variant metrics and sample sizes for each experiment, desired alpha, and number of comparisons. Include a strategy to control false discovery rate (FDR) and handle sequential analysis.

Technical-coding (medium): In C++ (server-side), design a function (pseudocode acceptable) to evaluate feature flags for a player. Requirements: deterministic percentage rollout, targeting by player attributes (region, subscription-tier), and caching evaluations for 60s. Describe API, hashing strategy, and thread-safety considerations.

MediumTechnical

Theoretical (medium): Compare and contrast qualitative player feedback (interviews, playtests) versus quantitative telemetry when deciding to ship a new social feature. When should each dominate decision-making, and how would you reconcile conflicting signals?

MediumSystem Design

29 practiced

System-design (medium): Design an experimentation and feature-flagging platform for a live game with 10M MAU. Requirements: client SDKs for Unity and native mobile, server-side evaluation, gradual rollout, immediate rollback, and real-time metric tracking to a dashboard used by PMs and designers. Outline components, data flow, and safety mechanisms.

MediumBehavioral

35 practiced

Behavioral (medium): Describe a time when you had to balance monetization goals with player experience (e.g., ads, pricing, gating). Explain how you collected player signals, modeled revenue impact versus retention, the decision you made, and the outcome.
