Technical practice
Suggested practice question: How would you architect an AWS GPU cluster for distributed training?
What to coverThe posting calls for GPU and accelerator selection, distributed training, networking, storage and scalable compute. Discuss how you would compare EC2, EKS and SageMaker options against workload performance, reliability, power and cost goals.
Suggested practice question: How would you find and resolve a data bottleneck in distributed training?
What to coverThe role calls for high-throughput storage and interconnect design using services including S3 and FSx/EFS. Explain what you would measure across data access, networking and accelerator utilization before changing the architecture.
Suggested practice question: How would you design a production model-serving foundation?
What to coverAddress serving capacity, scalability, latency, reliability and operational controls, all relevant to the advertised work. Explain how workload requirements would guide your choice of deployment approach rather than assuming one AWS service fits every model.
Suggested practice question: How would you integrate AI agents and workflows into an enterprise AI environment?
What to coverAI Agents & Workflow Integration is listed as a must-have skill, and the posting names Airflow, Kubeflow or comparable workflow tooling. As a preparation suggestion, describe how you would establish workflow interfaces, access controls and observability without assuming a particular agent framework is required.
Suggested practice question: How would you make AI platform and model releases repeatable?
What to coverThe role includes deployment automation and CI/CD for AI systems, models, data pipelines and platform components. Compare where Terraform or CloudFormation, containers and release checks would help, and how you would handle rollback and configuration changes.
Suggested practice question: How would you secure AWS AI infrastructure connected to enterprise systems?
What to coverThe posting names VPC and IAM and requires interoperability, security and compliance alignment. Discuss network boundaries, access design and how you would validate the architecture against client standards without assuming a specific regulatory regime.
Suggested practice question: How would you plan capacity and forecast the cost of growing AI workloads?
What to coverThe role calls for scaling plans, cost forecasts and optimization of performance, power consumption and cost. Explain which workload assumptions and utilization measures you would use, and how you would communicate trade-offs when demand changes.
Suggested practice question: How would you define observability and troubleshoot a production AI infrastructure incident?
What to coverThe posting calls for CloudWatch, InfraOps and MLOps monitoring, alerting, SLAs, SLOs and incident response. Describe signals that would distinguish infrastructure, pipeline and serving problems, then explain how findings would inform alerts and runbooks.
Suggested practice question: How would you assess an existing AI environment and document an architecture decision?
What to coverThe role requires identifying risks, bottlenecks and improvement opportunities and recording rationale, assumptions and dependencies. Walk through how you would compare alternatives across reliability, security, compliance, cost and operational complexity before recommending remediation.
Suggested practice question: When would you consider retrieval or vector-database infrastructure for an LLM workload?
What to coverLLM infrastructure, vector databases and retrieval pipelines are listed as good-to-have exposure, not core requirements. As an optional preparation suggestion, explain what workload evidence would justify these components and what serving, storage and operating costs they add.
Behavioural practice
Suggested practice question: Tell me about aligning stakeholders on a difficult infrastructure trade-off.
What to coverUse a real situation, your actions and the result to show how you translated business requirements into an architecture decision. Focus on communicating trade-offs such as performance, security, reliability and cost; do not assume all stakeholders initially agreed.
Suggested practice question: Describe how you led an engineering workstream while priorities competed.
What to coverUse situation, action and result to explain how you set technical direction, decided what to address first and coordinated delivery. The posting specifically calls for workstream leadership and managing priorities across initiatives.
Suggested practice question: Give an example of mentoring someone or improving a design through review.
What to coverDescribe the situation, the feedback or guidance you gave and the resulting change. Connect the example to the role’s design and code reviews, mentoring and promotion of engineering practices.
Suggested practice question: Tell me about responding to an infrastructure or production reliability issue.
What to coverUse situation, action and result to distinguish your troubleshooting contribution from the broader team’s work. Explain how you communicated impact, addressed the issue and used what you learned to improve monitoring or operations.
Suggested practice question: Describe a time you evaluated competing technologies or architecture patterns.
What to coverUse situation, action and result to show how you gathered evidence, weighed risks and documented a recommendation. The role explicitly involves technology evaluation, architecture decisions and communicating rationale to stakeholders.
