Technical Communication and Decision Making Questions

Focuses on the ability to explain technical solutions, justify trade offs, and collaborate effectively across engineering and non engineering stakeholders. Topics include articulating design decisions and their impact on reliability performance and maintenance, walking through solutions step by step, explaining algorithmic complexity and trade offs, asking clarifying questions about requirements, writing clear comments documentation bug reports and tickets, conducting and communicating root cause analysis, participating constructively in code reviews, and negotiating quality versus delivery trade offs with product and operations partners. Interviewers evaluate clarity of expression, reasoning behind decisions, and the ability to make choices that balance short term needs and long term quality.

During a design review, one engineer recommends eventual consistency cache invalidation while another argues for synchronous invalidation. As the architect, how would you facilitate the discussion, evaluate trade-offs (user correctness, latency, operational complexity), and drive to a decision that balances product and ops concerns?

You are asked to lead a cross-company initiative to standardize 'decision quality' across architecture reviews. Define a measurable framework with 5-7 dimensions (for example clarity, evidence, risk assessment) and explain how you would implement scoring, governance, and continuous improvement loops to raise decision quality over time.

You're assessing two database sharding strategies: range-based sharding and hash-based sharding. Explain to a cross-functional audience (engineers + product) the operational impacts of each approach, including rebalancing, hotspots, and query complexity, and which product requirements push you to one approach over the other.

A proposed architecture depends heavily on a single vendor-managed DB that has had intermittent regional outages. Prepare a balanced recommendation for leadership: (A) keep vendor with mitigations, (B) add multi-region fallback with another vendor, or (C) replace. Address cost, operational overhead, risk, SLA expectations, and decision criteria.
