This assessment helps me identify candidates for AI and machine learning roles. Your application and answers form part of my candidate review.

Taking part

Provide accurate application information and work through the questions at your own pace. Your résumé is optional. Completing the assessment does not guarantee an interview or an offer.

How the questions work

Each puzzle has a single accepted answer under its stated rules. Letter case and spaces are ignored. A correct answer opens a new puzzle and retires the previous one. Earlier questions cannot be reopened through the site.

Your current question is saved for the lifetime of your browser session, up to seven days from when the session began. Clearing your cookies or switching browsers can remove access to that session. Delays apply after incorrect answers.

After completion

Once all your answers are verified, you receive a unique reference ID. Save it and email sahil@mellivo.ai with that ID in the subject line. The completion page provides an email link with the recipient and subject filled in. You write and send the message yourself.

Timing and review

I can review your application, the generated answers for your session, submission counts and progress. Time is measured from when a question opens until a correct answer arrives, including research, breaks and time away. Timing is context for my review, not a measure of continuous activity.

Respect the space

Use your own session. Do not attempt to access another candidate’s information or the private dashboard, interfere with the service, or upload files you do not have permission to share. Follow the instructions supplied with each puzzle.

Your information

The Privacy Policy explains what is saved and how it is used. The public assessment at 0xce5.com is hosted on Cloudflare. Availability can be interrupted by maintenance or service limits. A local development preview may be unavailable when its server is stopped.
