Describe ML projects and tech choices

Q: Describe ML projects and tech choices

This question evaluates a candidate's ability to communicate end-to-end machine learning project experience, covering problem definition, data sources and preprocessing, model architecture and training, evaluation metrics, deployment, and measurable impact while also probing justification of technology choices and trade-offs.

Q: How do I approach ML System Design interview questions?

ML System Design questions require understanding of core concepts and practice. PracHub provides solutions with explanations to help you master ml system design interviews.

Question

ML Project Overview and Deep Dive (HR Screen)

Context

You are interviewing for a Machine Learning Engineer role. Provide a concise, structured overview of your primary ML project and briefly summarize one or two other major projects. Then, deep-dive into the technologies behind one selected project, explaining choices, trade-offs, and limitations.

Prompts

Primary ML Project (concise overview)
- Problem definition and business objective
- Data sources and preprocessing
- Model architecture or algorithms
- Training setup (loss, sampling, hardware, orchestration)
- Evaluation metrics (offline and online/A-B)
- Measurable outcomes/impact
Other Projects (1–2 summaries)
- Objective and high-level approach
Deep Dive (choose one project)
- Key technologies/frameworks for: data pipeline, model training, deployment/serving, infrastructure
- Why these were chosen over alternatives
- Trade-offs and limitations
