Contract Assistant Answers Well Question Explained
This worked AI Engineer Interview practice question tests System Reasoning. Try the answer first, then review why C is the best choice.
Short answer
The correct answer is C. Upstream of retrieval: whether footnote and table text survives OCR, structure extraction, and chunking at all..
Retrieval can only rank text that exists in the index; layout-heavy regions often die in ingestion, which makes downstream scores look 'healthy' on the text that survived. The key is to match the exact action in the prompt to the tool, command, or concept that performs that action directly. Here, C. Upstream of retrieval: whether footnote and table text survives OCR, structure extraction, and chunking at all. is the only option that satisfies the scenario without adding unrelated behavior.
The Question
A contract assistant answers well from normal paragraphs but misses obligations in footnotes and scanned tables. Retrieval scores look healthy. Where do you look first?
Why C is correct
Retrieval can only rank text that exists in the index; layout-heavy regions often die in ingestion, which makes downstream scores look 'healthy' on the text that survived. The key is to match the exact action in the prompt to the tool, command, or concept that performs that action directly. Here, C. Upstream of retrieval: whether footnote and table text survives OCR, structure extraction, and chunking at all. is the only option that satisfies the scenario without adding unrelated behavior.
Why the other options are wrong
Option A does not match the requirement in the prompt. The correct answer is C because Retrieval can only rank text that exists in the index; layout-heavy regions often die in ingestion, which makes downstream scores look 'healthy' on the text that survived.
Option B does not match the requirement in the prompt. The correct answer is C because Retrieval can only rank text that exists in the index; layout-heavy regions often die in ingestion, which makes downstream scores look 'healthy' on the text that survived.
Option D does not match the requirement in the prompt. The correct answer is C because Retrieval can only rank text that exists in the index; layout-heavy regions often die in ingestion, which makes downstream scores look 'healthy' on the text that survived.
Key idea: System Reasoning
Every question is a production situation an AI engineer interviewer can put to you: a failing endpoint, a cost spike, an agent that loops, an eval that disagrees with users. The best answer is almost always the one that measures or contains the problem before it changes the model or the prompt. If you miss a question, note which habit it tests: decompose before you fix, put the security boundary where the side effect happens, and trust an eval only after you check what it covers.
