Skills to revise

Refine a model design
Practice presenting a proposed LLM architecture, its parameter choices, and a revision when project needs change. This directly reflects the stated responsibility to design and continually refine language models.
Diagnose performance results
Given hypothetical model metrics, identify a likely limitation, propose a specific improvement, and state how you would check whether it worked. The posting requires analyzing performance metrics and implementing improvements.
Plan for training scale
Work through a hypothetical increase in training-data or model size: identify what could strain a distributed setup and propose adjustments to test. This practices the distributed-training and scalability challenges named in the posting.
Explain a deployment trade-off
Draft a brief decision note for a hypothetical model deployment constraint, stating the performance–scalability trade-off and an approach to validate it. The posting explicitly mentions managing deployment challenges; the scenario is a preparation exercise, not a stated project.
Advise and mentor on a technical decision
Practice explaining an architecture recommendation to another team, addressing objections, then restating the reasoning for a junior colleague. This prepares for the posting’s influencing, advisory, cross-team problem-solving and mentoring responsibilities.
