01Clarify objective, users, constraints, and failure tolerance.
02Cover layout, OCR, visual grounding, tables 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 multimodal document understanding: judgment, I would analyze layout, OCR, visual grounding, tables, compare alternatives on quality, latency, cost, and risk, and validate on representative slices before a monitored rollout.

layout
OCR
visual grounding
tables

Requires scenario-specific numbers
Should include relevant personal experience

alternative answer

I would start with the riskiest assumption in multimodal document understanding: judgment, 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
