Why generic interviews fail for AI/ML hiring

The titles "AI Engineer," "ML Engineer," and "Data Scientist" are often used interchangeably — but they represent meaningfully different skill sets, day-to-day work, and technical depth requirements.

An ML engineer building training pipelines and managing model registries needs to be evaluated very differently from a data scientist running business experiments or an AI engineer building RAG systems on top of foundation models.

When the same interview gets applied to all three, the result is unreliable signal. Candidates who can talk fluently about one area look strong across all three. Our evaluations are designed around the specific competencies each role actually requires.

What distinguishes each role

AI Engineer

LLM-powered product development — RAG systems, inference infrastructure, prompt pipelines, AI integration.

ML Engineer

Model training and deployment — feature pipelines, experiment infrastructure, MLOps, production serving.

Data Scientist

Statistical analysis and experimentation — A/B testing, predictive modeling, business analytics, insight generation.
