AI in interviews

high confidence

Glean's job postings say every loop includes a short AI-focused exercise or discussion about how you design and use AI in your work. They don't say whether AI assistants are allowed in live coding rounds, so assume not unless your recruiter says so.

Typical interview loop

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

  1. Recruiter and hiring manager screens

    Focus: Fit, motivation, project depth

    A short recruiter call on background and logistics, then a roughly 45-minute hiring manager call on past projects and why you made the technical calls you did.

  2. Technical phone screen

    Focus: DSA and clean code

    About an hour of live coding on a shared editor, usually one medium-to-hard problem plus a talk about trade-offs and complexity.

  3. Onsite coding and practical build

    Focus: Coding speed, code organization

    Harder algorithm rounds plus a timed session where you build a small working program from an empty file, graded on structure, whether it runs, and speed.

  4. Search system design

    Focus: Search architecture, trade-offs

    A roughly 60-minute design discussion about search-style systems, such as indexing many workplace apps, respecting document permissions, and ML ranking.

  5. ML / RAG round (ML-track roles)

    Focus: Retrieval, ranking, evaluation

    For ML roles, a round on embeddings, retrieval, reranking and evaluation, where you're expected to back model and chunking choices with metrics.

  6. AI-focused exercise and behavioral

    Focus: AI fluency, values

    A short exercise or conversation on how you think about, design and use AI in your role, alongside a behavioral round on ownership and collaboration.
