Technical practice
How would you explain the main bottlenecks in LLM inference?
What to coverSuggested preparation: Distinguish model execution from token generation and explain how workload shape affects latency, throughput and memory use. Discuss how you would measure a bottleneck before choosing an optimization.
How would you scope a customer proof of concept for generative AI inference?
What to coverSuggested preparation: Start with the customer's technical needs, workload and criteria for a useful result. Explain how you would choose a representative test, record a baseline and present trade-offs without treating a proof of concept as a production guarantee.
How would you investigate an inference deployment that cannot use its intended GPU resources in Kubernetes?
What to coverSuggested preparation: Walk through the container, workload configuration, orchestration state and GPU allocation before changing the deployment. Explain how Multi-Instance GPU management could affect resource availability and how you would verify the cause.
What would you monitor to diagnose an AI inference deployment?
What to coverSuggested preparation: Connect application behavior, container and Kubernetes state, and GPU utilization to the symptoms you are investigating. Explain how you would use observations to distinguish a serving issue from a resource or orchestration issue.
How would you analyze inference performance alongside power efficiency on Kubernetes?
What to coverSuggested preparation: Define comparable workloads and measurements for performance and power use, then explain how you would check the reliability of the results. Discuss the trade-off between faster inference and greater resource or power consumption.
How would you use Python and a deep learning framework to isolate an inference performance problem?
What to coverSuggested preparation: Describe how you would reproduce the workload, inspect model and application behavior, and profile before modifying code. Use PyTorch or TensorFlow as a concrete example, while separating framework-level effects from deployment effects.
How would you decide whether NVIDIA inference software is appropriate for a customer solution?
What to coverSuggested preparation: Be ready to discuss relevant experience with NIM, Dynamo, TensorRT or TensorRT-LLM, which the posting lists as preferred rather than required. Explain how you would evaluate fit against the workload, integration effort and measured results instead of assuming a tool will improve performance.
What changes when an inference proof of concept moves toward production?
What to coverSuggested preparation: Discuss repeatable deployment, monitoring, reliability and optimization against representative demand. Explain which proof-of-concept findings you would revalidate under production conditions; production inference experience is listed as preferred.
How would you profile and test a suspected performance issue in inference software?
What to coverSuggested preparation: Describe a controlled benchmark, a profiling approach and tests that guard against regressions. If drawing on C/C++ experience, distinguish measured code-level improvements from changes elsewhere in the system; those skills are preferred in the posting.
When might distributed or parallel execution help an inference workload?
What to coverSuggested preparation: Explain the potential benefits and the coordination, communication and resource costs. Frame this as an area to review if relevant to the workload: the posting lists parallel and distributed computing familiarity as preferred.
Behavioural practice
Tell me about a time you translated an ambiguous customer need into a technical approach.
What to coverSuggested preparation: Use a real situation, the questions you asked and the actions you took to define the solution. State the result and how you determined whether it met the customer's need.
Describe a time you coordinated engineering, product and customer-facing stakeholders on a technical decision.
What to coverSuggested preparation: Give the situation, your specific role and how you handled differing priorities. Close with the decision, its result and what you communicated to each group.
Tell me about a customer proof of concept that encountered a technical obstacle.
What to coverSuggested preparation: Explain the situation, how you diagnosed the obstacle and what you did with the customer or technical team. Describe the observed result without overstating what the proof of concept established.
Describe a time you presented complex performance findings to a mixed audience.
What to coverSuggested preparation: Identify the audience, your communication choices and the evidence you used. Explain the resulting decision or feedback, including any uncertainty you made clear.
Tell me about a time you adapted your approach while working with specialists from different disciplines.
What to coverSuggested preparation: Use a real example involving distinct technical perspectives, such as development and data science, if applicable. Explain the situation, what you changed in your collaboration and the result.
