The SDE 2 rounds, in order

  1. Low-level design / machine coding · 90 min

    Machine coding: about 90 minutes to build and submit a working app, then a 30-minute walkthrough of the code, sometimes the next day.

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

  2. Coding (DSA) · 45 min

    Problem Solving & Data Structures (PSDS): usually two medium problems, often DP, trees, recursion or graphs; some candidates get a second PSDS round.

    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. System design (HLD) · 60 min

    A design round mixing LLD with some HLD for SDE-2; SDE-3 goes deep on both.

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

  4. Hiring manager · 45 min

    Past projects, the architecture of your current org, and behavioral questions.

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