Technical practice
Designing Robust Data Pipelines for AI
What to coverExplain how you would design a data pipeline to feed a RAG system, ensuring data freshness and quality. Discuss how you handle schema evolution and potential bottlenecks when integrating with live enterprise infrastructure.
State Management in Multi-Agent Systems
What to coverWhen using frameworks like LangGraph or CrewAI, how do you manage state across multiple agent turns? Describe the trade-offs between centralized state stores and distributed memory patterns in a production environment.
LLM-Native Metrics and Performance Optimization
What to coverBeyond standard latency, what specific metrics would you track for an LLM-based application? Explain how you would optimize for tokens-per-second and cost-per-request without sacrificing output quality.
Integrating APIs with Enterprise Infrastructure
What to coverDescribe the process of building secure connective tissue between a cloud-based AI service and a customer's legacy backend. Focus on authentication, rate limiting, and ensuring the integration is resilient to network failures.
Granular Tracing for Debugging Agentic Workflows
What to coverWhy is granular tracing critical for debugging non-deterministic AI agents? Suggest how you would implement observability to identify where an agentic chain fails or produces hallucinations.
Transitioning Prototypes to Production
What to coverWhat are the key differences between a rapid AI prototype and a production-grade solution? Discuss considerations for security, scalability, and maintainability when moving code into a customer environment.
Programming Language Selection for Backend Systems
What to coverGiven the choice between Python, Go, or Rust for a backend component of an AI system, how do you decide which to use? Address performance, developer velocity, and ecosystem support for ML libraries.
Handling Unstructured Data in Cloud Databases
What to coverHow do you approach indexing and retrieving unstructured data from cloud databases for use in AI workflows? Discuss the role of vector embeddings and metadata filtering in improving retrieval accuracy.
Behavioural practice
Managing Ambiguity in Customer Environments
What to coverDescribe a time you had to solve a technical problem where the requirements were unclear or the environment was unfamiliar. How did you gather the necessary information and align with stakeholders to deliver a solution?
Providing Feedback to Product Teams
What to coverGive an example of when you identified a recurring technical barrier or product limitation. How did you document and communicate this feedback to ensure it could influence future development?
Collaborating with Cross-Functional Teams
What to coverTell me about a time you worked with a team that had different technical priorities than your own. How did you bridge the gap to ensure the project met both customer needs and technical best practices?
Taking Ownership of Full-Stack Roadblocks
What to coverDescribe a situation where you encountered a significant technical roadblock that was outside your immediate area of expertise. What steps did you take to overcome it and what was the final outcome?
