Multilingual RAG for a European Customer-Support Knowledge Base
Overview
What this challenge is about.
Multilingual RAG for a European Customer-Support Knowledge Base. Expert-level challenge in code. Writing production code that solves real engineering problem...
The Brief
What you'll do, and what you'll demonstrate.
Build a multilingual RAG that retrieves across 4 languages and answers in the query language with original-language citations, meeting per-language quality bars.
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 embedding models to cross-lingual retrieval
- Design per-language evaluation that surfaces minority-language weaknesses
- Manage citation hand-off between source language and answer language
- Communicate readiness to an enterprise customer's leadership
