developer platform

A platform metrics question. Token volume is the obvious answer and the incomplete one. The interviewer wants the developer funnel, reliability, economics and migration health in one coherent set.

A role-understanding question common in lab interviews. A crisp answer shows you know who the customers are, what decisions you own, and how success is measured.

A launch question where positioning, pricing, evaluation and capacity all have to line up. The interviewer wants to see you avoid cannibalising the wrong tier and give developers what they need to adopt it.

Embeddings are infrastructure that customers store and rebuild around. The interviewer wants retrieval quality on real tasks, multilingual coverage, cost, and above all a plan for version changes, because switching embeddings means re-indexing everything.

A principal-level platform design. Customers want better results on their tasks; most of them would get there faster without fine-tuning. The product has to guide them, protect their data, preserve safety, and survive base model upgrades.
