• Fine-tuning methodologies – Parameter-efficient fine-tuning approaches including LoRA, QLoRA, and reinforcement learning with verifiable rewards.
• Hallucination reduction – Strategies for grounding model outputs, managing ambiguous data, and verifying factual accuracy.
• Advanced concepts (less common) – Custom reward model design, multi-modal document layout analysis, and decentralized fact aggregation.

Example questions or scenarios:

• "How would you fine-tune an open-source LLM to extract specific contractual clauses from noisy, multi-page legal documents?"
• "Walk through your approach for evaluating hallucination rates in a generative QA system."

Systems Architecture and RAG Pipelines

This evaluation focuses on your ability to design scalable, production-ready machine learning infrastructure. You will be tested on how you handle data ingestion, embedding generation, and high-throughput retrieval.

Be ready to go over:

• Vector databases and search – Experience with tools like Pinecone, Weaviate, FAISS, Milvus, or Elasticsearch for semantic search.
• Retrieval frameworks – Implementing and optimizing pipelines using LangChain, LlamaIndex, or custom retrieval architectures.
• Scalability and efficiency – Managing large-scale embedding pipelines, reducing inference latency, and controlling compute costs.
• Advanced concepts (less common) – Distributed vector indexing, hybrid keyword-semantic search re-ranking, and low-latency caching layers.

Example questions or scenarios:

• "Design an end-to-end RAG system that can query tens of millions of historical medical records with sub-second response times."
• "How do you handle embedding model versioning and index migration in a live production environment?"

Software Engineering and Coding Rigor

EvenUp expects machine learning engineers to write clean, maintainable, and efficient production code. This area tests your fundamental programming abilities and software design principles.

Be ready to go over:

• Python proficiency – Writing robust, idiomatic Python code for data processing and API integration.
• Algorithmic problem-solving – Tackling standard data structure and algorithm challenges efficiently within time constraints.
