The SDE 2 rounds, in order

  1. Phone / recruiter screen · 30 min

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

    At SDE 2: One or two problems, a little faster. Some companies mix in a design question.

  2. 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 2: Two or three rounds at medium to hard level. You are expected to reach the optimal approach with fewer hints and to test without being asked.

  3. Coding (DSA) · 60 min

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

    At SDE 2: Two or three rounds at medium to hard level. You are expected to reach the optimal approach with fewer hints and to test without being asked.

  4. Team-specific round · 60 min

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

    At SDE 2: Debugging, integration or code review rounds at product companies.

  5. Team-specific round · 60 min

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

    At SDE 2: Debugging, integration or code review rounds at product companies.

  6. System design (HLD) · 60 min

    System design that leans on clean API and data-model design, reliability and idempotency; new-grad loops may skip it.

    At SDE 2: Present at most companies. A sound end-to-end design with sensible components and basic scaling is enough.

  7. Hiring manager · 45 min

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

    At SDE 2: Ownership of features, handling production issues, working with product and other teams.
