AI-training platforms hire people to review, write and check AI output, and each has its own way of screening applicants. Some use an AI interviewer, some use a written test and some use a skills screening. Check the platform’s own page for the current steps, and practise speaking your answers out loud. Checked 30 October 2026.
The platforms with a guide of their own
- micro1: a conversation with an AI recruiter called Zara. Its terms ask for your own answers.
- Mercor: an AI interview of about 20 minutes, recorded, with free practice interviews.
- Alignerr: some jobs include a Zara interview or domain assessments.
Outlier
Outlier’s homepage lists four steps: create your profile, import and review skills, verify your identity, and verify skills. It says general onboarding takes about 30 to 90 minutes and includes skill screenings, and that project onboarding varies. It says you need a valid ID, a phone from your country, a resume and a LinkedIn profile. We could not confirm Outlier’s rules on AI help from its own pages, and we could not read its monitoring notice, so we do not describe them. Read Outlier’s Community Guidelines and Terms of Use yourself. Checked 30 October 2026. For general preparation, see our Outlier skill screening guide.
DataAnnotation
DataAnnotation’s FAQ says the Starter Assessment can be taken only once, that you choose a track at signup, and that most take about an hour while specialised assessments can take one to two hours. It lists tracks such as general, multilingual, coding, STEM and professional. We could not confirm its rules on AI help from its own pages. Because you get one attempt, read the instructions slowly before you begin. Checked 30 October 2026. Our DataAnnotation assessment guide covers how to prepare.
Handshake AI
Handshake AI’s page lists five steps: apply and verify your identity, get matched to a project, take the training, contribute your expertise and get paid. It says applicants must be based in the US with work authorization that Handshake can support. We could not find an interview step or a rule on AI help on that page, so we do not describe either. Checked 30 October 2026.
What these steps have in common
Across the platforms, the application usually involves proving who you are, showing you know your subject and showing you follow written instructions. Three habits help with all of them.
- Read the instructions twice. Many screenings reward careful reading as much as knowledge.
- Explain your reasoning. Say why an answer is right, and say what you would check.
- Admit uncertainty. Saying you are not sure, and how you would find out, is better than guessing.
Set up your space
- Test your microphone and camera before any recorded or live step.
- Choose a quiet room, and tell the people around you.
- Use a computer and a stable internet connection, and close other programs.
- Keep your resume and ID ready.
How to practise with PrepHint AI
- Add or build your resume. Resume Maker is free forever.
- Create a mock interview for the role. Describe the platform’s job in your own field.
- Practise out loud. The AI mock interviewer speaks to you, and you answer by voice.
- Read the transcript. Look for rambling, pauses and filler words.
Every new account gets 15 free minutes of live help and 1 mock interview, with no card needed. See pricing. Mercor also offers free practice interviews of its own, so try those too.
Before you go on
PrepHint AI also has live answers. We could not confirm every platform’s rule on AI help from its own pages, so treat AI help as not allowed unless a platform’s rules clearly say otherwise. Whether you follow those rules is your decision and your risk. PrepHint AI supplies the software and is not liable for what happens on another platform.
PrepHint AI also works as an interview copilot on video calls, wherever AI help is allowed.
PrepHint AI is not connected to any of the platforms named here.
