Intelligent Document Processing & Workflow Automation

Design an agent that processes incoming documents (invoices/claims), extracts and validates data, and pushes it downstream — replacing a manual team.

Key Requirements

01Classify → parse/OCR → extract fields → validate (business rules)
02Confidence-gated straight-through vs human-review routing
03Threshold set by cost-of-error vs cost-of-review
04Correction flywheel; audit trail; compliance
05Fallback for unseen document types; error-escape monitoring

Rubric must-haves

0/3

Has an extraction (model) step
Has a validation tool / rules
Has a human-review queue for low confidence

These checks are the structure score, 30% of your total. They update as you draw.

Practise it like the real round

45-minute timer paced through requirements, design and deep dive. The follow-up questions stay hidden until the last phase, and solution hints are off.
