The Brief
What you'll do, and what you'll demonstrate.
Build a cross-lingual RAG QA system that retrieves across 3 languages and answers in the asker's language with citations.
This is not a coding exercise. It is the work a software engineer does between a Jira ticket and a merged PR. That distinction matters to every hiring manager who has seen candidates solve LeetCode problems and none who have shipped production code under real constraints.
When you finish, you will have something most graduates do not: a real-world deliverable, verified by Ewance, that you can show to a hiring manager and say "I did this. Here is the proof."
Earning criteria — what you'll demonstrate
- Apply multilingual embeddings to a real cross-lingual retrieval problem
- Build a citation-bearing RAG pipeline
- Evaluate RAG with separate retrieval and answer metrics
- Plan a deployment for a multilingual internal-tools audience
