The SDE 1 rounds, in order

  1. Phone / recruiter screen · 30 min

    A recruiter call on background, a concrete 'why Stripe' and role fit.

    At SDE 1: Usually one medium problem. Explain your idea before coding and test by hand at the end.

  2. Online assessment · 60 min

    Interns and new grads often get an online assessment with one multi-part problem.

    At SDE 1: The main filter for new grads and campus drives. Expect two medium problems, sometimes one hard. Passing all test cases on both usually gets you to the next round.

  3. Coding (DSA) · 60 min

    The technical screen is one long, multi-part, real-world prompt (CSV parsing, ledgers) that you pair-code and test yourself.

    At SDE 1: The largest part of the loop: often three coding rounds. Medium problems, sometimes one hard. Correct, clean code and clear reasoning matter more than speed.

  4. Coding (DSA) · 60 min

    Onsite coding is scenario-driven and light on algorithms; working code is the strongest signal.

    At SDE 1: The largest part of the loop: often three coding rounds. Medium problems, sometimes one hard. Correct, clean code and clear reasoning matter more than speed.

  5. Team-specific round · 60 min

    Bug Bash: diagnose and fix a failing test or issue in an unfamiliar codebase.

    At SDE 1: Mostly language and CS fundamentals deep dives (Java internals, databases, OS).

  6. Team-specific round · 60 min

    Integration: build a small feature against a given API in an unfamiliar repo using its docs.

    At SDE 1: Mostly language and CS fundamentals deep dives (Java internals, databases, OS).

  7. Hiring manager · 45 min

    A behavioral round with the hiring manager on ownership, collaboration and the operating principles.

    At SDE 1: Motivation, learning, a project walk-through and sometimes CS fundamentals.
