The SDE 2 rounds, in order

  1. Phone / recruiter screen · 30 min

    A recruiter call on background, the target business line and why Uber.

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

  2. Online assessment · 90 min

    A timed online assessment scored on hidden tests; problems are hard and must pass every case.

    At SDE 2: Used by some companies for experienced hires (Amazon, Uber, Salesforce, Oracle). The bar is the same as for SDE 1 but the time is often shorter.

  3. Coding (DSA) · 60 min

    The business phone screen mixes coding with some design, and largely sets the level you interview for.

    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. Coding (DSA) · 60 min

    Onsite Coding 1 covers algorithms and data structures at medium-hard level; graphs and DP are common.

    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.

  5. Low-level design / machine coding · 60 min

    Coding 2, 'Depth in Specialization', is often machine coding or object-oriented design for backend roles, such as file-system commands with concurrency.

    At SDE 2: The core round at many product companies: working, modular, extensible code with validation, error handling and tests, finished on time.

  6. System design (HLD) · 60 min

    System design focused on scale, async processing and failure handling, sometimes starting from your own past work.

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

  7. Hiring manager · 60 min

    Collaboration & Leadership: a behavioral round, usually with the hiring manager, on past projects and conflicts.

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