AI in interviews

high confidence

Assume AI is not allowed on any live interview question unless you're told otherwise. Some designated parts of the process, including some at-home or virtual assignments, invite AI use, while others explicitly ban it to test your fundamentals.

Typical interview loop

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

  1. Online assessment

    Focus: Coding fundamentals

    A CodeSignal skills test that you must pass to move on; experienced hires may get a live coding screen instead.

  2. Recruiter screen

    Focus: Motivation, role fit

    A 30-minute call about your interests, role expectations and what the technical rounds will look like.

  3. Technical phone screen

    Focus: DS&A

    A one-hour live session with one or two coding problems.

  4. Coding rounds

    Focus: Algorithms

    Two medium-level data structures and algorithms rounds, often framed around Pinterest data like pins and graphs.

  5. ML system design rounds

    Focus: Recsys, real-time ML

    Usually two rounds on designing real-time ML systems such as home-feed ranking or fraud detection.

  6. Hiring manager / behavioral

    Focus: Collaboration, values

    A conversational round on collaboration, handling feedback and fit with Pinterest's values.
