Your question is Chunking and PDF Loading Constraints. Take a moment with it on the right.

Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).

You need to log in / sign up to chat or submit.

Problem

What if we increase chunk size? How will you load the pdf if your company doesn't allow pdf loaders?

Explain how you would build a practical PDF ingestion pipeline without using framework-specific PDF loader classes. Cover approved document extraction, OCR fallback, page-aware chunking, metadata preservation, idempotent loading, validation, retries, and monitoring. Discuss the trade-offs of larger chunks for retrieval quality, token limits, memory usage, embedding cost, and downstream latency.
