AI in interviews

high confidence

External resources, AI included, are not allowed in interviews unless you're told otherwise. The ML loop does include a dedicated AI-assisted coding round, and interviewers say which rounds allow AI.

Typical interview loop

How Snap usually runs it for applied AI and LLM engineer roles.

  1. Initial interview

    Focus: Values, coding or ML basics

    A screen pairing a values-based behavioral question with role skills, which may include coding fundamentals or ML domain knowledge.

  2. ML fundamentals

    Focus: ML theory, model trade-offs

    A technical round testing the depth and breadth of your ML theory, including why you made the modeling choices in past projects.

  3. Applied ML (model design)

    Focus: Problem framing, metrics, features

    Turn a business problem into an ML problem: pick metrics, data sources and features, then propose a model.

  4. ML system design

    Focus: Production ML architecture

    An end-to-end design of a scalable, ML-heavy production system covering latency, inference, scale and monitoring.

  5. AI-assisted coding

    Focus: Problem solving with AI

    A DS&A problem solved on HackerRank with an AI assistant, judged on how deliberately you use it to generate, debug and revise code.

  6. General coding

    Focus: CS fundamentals

    A standard algorithms and data structures round in your chosen language, without AI.
