Technical Leadership and Architectural Influence Questions

Demonstrating leadership in technical decisions at the architecture or system level. Candidates should prepare concrete examples where they identified architectural problems, evaluated alternative solutions and trade offs, proposed a preferred design, gained buy in from engineers and stakeholders, and drove implementation. Discuss systems thinking and long term impact on team velocity, code quality, reliability, and product features. Include examples of championing new tools or frameworks, leading migrations or refactors, negotiating trade offs between time to market and technical debt, and occasions when you reversed a decision based on new data. Emphasize communication of complex technical ideas, consensus building with peers, and measurable outcomes.

Propose an architecture and deployment plan for a robust feature-flagging system controlling model behavior (e.g., disabling model variants or switching feature groups). Ensure low-risk toggling, auditability, targeting/bucketing, distributed consistency, and rapid rollbacks across distributed inference services.

Tell me about an occasion when you reversed an architectural or tooling decision after observing new metrics or incidents. What prompted the reversal, how did you communicate the change to teams and stakeholders, and what were the quantitative outcomes of that reversal?

How would you design and run an architecture review board for ML services across multiple teams? Define approval criteria for changes, SLAs for board responses, emergency fast-paths for incident-driven changes, documentation standards, and practices to ensure governance doesn't block velocity.

Define model versioning for production ML systems. What artifacts should be versioned (weights, code, config, env), how would you name and track versions, and why is versioning important for reproducibility, rollback, auditing, and compliance?

How would you champion adoption of a new inference framework (for example, migrating from TensorFlow Serving to TorchServe or a custom gRPC runner) across multiple teams? Describe evaluation criteria, a pilot plan, risk mitigation strategies, and success metrics to determine whether to roll it out company-wide.
