Trade Off Analysis and Decision Frameworks Questions

Covers the practice of structured trade off evaluation and repeatable decision processes across product and technical domains. Topics include enumerating alternatives, defining evaluation criteria such as cost risk time to market and user impact, building scoring matrices and weighted models, running sensitivity or scenario analysis, documenting assumptions, surfacing constraints, and communicating clear recommendations with mitigation plans. Interviewers will assess the candidate's ability to justify choices logically, quantify impacts when possible, and explain governance or escalation mechanisms used to make consistent decisions.

Your mobile user base complains of high tail latency. As PM choose between three initiatives: A) add edge CDN, B) implement backend performance optimizations, C) invest in client batching. Build an evaluation approach including experiments, expected impact, and rollback plan. How would you A/B test each option given limited engineering capacity?

You need to model the costs and latency impacts of a multi-region deployment under different traffic growth scenarios. Describe how you would perform a scenario analysis: which variables to vary, how to present the results to executives, and what stoplight thresholds you would set for deciding when to add new regions.

Compare application-side memoization versus a shared distributed cache across services for reducing duplicate compute. Evaluate tradeoffs on consistency, memory footprint, caching granularity, and cross-service reuse. Recommend which to start with and explain the migration path from one approach to the other.

A partner integration team asks you to implement a global rate limiter. As a PM, explain the tradeoffs between per-user, per-API-key, and global rate limiting approaches and when you would recommend each. Include considerations for fairness, implementation complexity, and monitoring.

Design a throttling strategy when fairness is a priority for multi-tenant API consumers, but you also need simplicity to implement quickly. Compare token-bucket, leaky-bucket, and rate-limited quotas by tenant. Include how you would measure fairness and what SLOs matter for degraded performance.
