Eightfold AI online assessment questions

A note on accuracyHiring loops change by role, level, location, and team. Treat recruiter instructions as the source of truth; this guide focuses on preparation signals supported by the current tagged-question dataset.

02 / Rehearsal

Run a 90-minute mock assessment

  1. 01

    10 minutes — scan and classify

    Read every prompt, note constraints, and order the questions by confidence rather than attacking the first one blindly.

  2. 02

    55 minutes — solve for correctness

    Secure the straightforward cases first, then improve complexity only when the constraints demand it.

  3. 03

    15 minutes — adversarial testing

    Test empty inputs, duplicates, large values, ordering assumptions, and off-by-one boundaries.

  4. 04

    10 minutes — review and submit

    Remove debug output, re-check complexity, and make sure every required function signature and return type is correct.
