The SDE 2 rounds, in order

  1. Phone / recruiter screen · 30 min

    A recruiter screen on projects and experience.

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

  2. Coding (DSA) · 60 min

    Two easy-to-medium problems, sometimes wrapped in a REST endpoint with validation and error handling.

    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. Team-specific round · 60 min

    A Java and tech deep dive: streams, multithreading, HashMap internals, SOLID, Spring Boot, Kafka, Redis and SQL.

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

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

    Some SE III loops include a medium LLD problem with Java concurrency follow-ups.

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

  5. System design (HLD) · 60 min

    System design for SE III and above, e.g. inventory management or a read-heavy multi-region feed.

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

  6. Hiring manager · 60 min

    A project deep dive plus behavioral questions, sometimes with a design or coding question.

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