01Clarify objective, users, constraints, and failure tolerance.
02Cover attention efficiency, compression, kernel optimization, evaluation in a causal structure.
03Compare at least two credible approaches.
04Specify evaluation, rollout, monitoring, and rollback.

Reference answer

strong answer

I would begin by defining the target outcome and acceptable failure boundary. For Transformer efficiency, I would analyze attention efficiency, compression, kernel optimization, evaluation, compare alternatives on quality, latency, cost, and risk, and validate on representative slices before a monitored rollout.

attention efficiency
compression
kernel optimization
evaluation

Requires scenario-specific numbers
Should include relevant personal experience

alternative answer

I would start with the riskiest assumption in Transformer efficiency, create the cheapest discriminating experiment, then use the evidence to choose an architecture and release threshold.

experimentation
risk-first sequencing
decision clarity

Needs deeper implementation detail
