AI Engineering Motivation and Role Fit Questions
Evaluate why the candidate wants to work in AI engineering and how that interest connects to the specific companys AI vision and the open role. Topics include preferred AI subfields, types of problems that excite the candidate, relevant past projects, and how their technical interests and ethics align with the companys AI initiatives or research directions. Candidates should explain why AI work matters to them, which applications or models they care about, and how their experience would help solve the companys AI challenges in a way that feels authentic rather than rehearsed.

We plan to deploy a large language model behind a latency-sensitive API. As the SRE, propose an inference architecture that balances cost, latency, and reliability across peak traffic. Include autoscaling approach, caching and batching strategies, model sharding or ensemble tradeoffs, fallback behaviors, and the deployment topology (multi-AZ, regional endpoints).

You join a team where production models show slowly degrading accuracy over a period of weeks. Outline an incident response plan tailored to model degradation that covers detection, triage, mitigation, rollback, root-cause analysis, and differentiates short-term vs long-term fixes. Highlight SRE-specific actions and ownership during each phase.

How would you handle secrets and model artifacts in a multi-tenant environment where models require access to private feature stores and third-party APIs? Discuss authentication and authorization (workload identities), fine-grained access control, artifact signing and provenance, encryption at rest/in transit, and auditability requirements.

Design a global, multi-region model serving platform that must guarantee 99.95% availability, p95 latency under 150ms for local users, and comply with data residency requirements. Describe regional placement, model synchronization patterns, failover strategies, consistent routing, data segregation, CI/CD for model rollouts, chaos/perf testing, and monitoring strategy.

You discover a subtle bias introduced by a feature in the inference pipeline that disproportionately harms a protected group. Describe your operational response: immediate containment steps, technical mitigations (rollback, feature gating, filters, retraining), stakeholder communication with ethics and legal teams, and process and automation changes you would implement to prevent recurrence.
