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

  2. Coding (DSA) × 3 · 45 min

    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. Hiring manager · 60 min

    The final conversation, historically called the 'As Appropriate' (AA) interview, covers background and behavioral questions and often one open design question.
