Applying to Invisible, step by step
Researched August 2026Browse projects and join the Meridial expert network at meridial.ai, complete a detailed profile, and if your expertise matches a project you are invited to pass a skills assessment before starting paid, twice-monthly contractor work.
Who can join
- Worldwide remote is possible, but projects are matched to your profile, language, and location, so you are only shown and invited to projects that fit. Specific per-country availability shifts as projects open and close.
- Strong written English. It is a stated expectation across the trainer roles and central to the work (reviewing and writing model outputs).
- You work as an independent contractor, not an employee of Meridial or Invisible Technologies; you accept or decline each project.
- Two tracks: generalist roles marketed as 'no experience required' (reviewing/error-checking AI outputs), and specialist roles that require real domain expertise (e.g. law, STEM, finance, software engineering, linguistics). Most projects are specialist.
- Reliability and availability during a project's scheduled hours; ability to follow structured processes. Prior operations/QA or data-workflow experience is preferred and this is not aimed at complete beginners.
- No joining, membership, or application fee is charged to experts (standard for worker-side expert networks). Note: Meridial's own FAQ does not explicitly state a fee policy, so treat this as unconfirmed by official documentation.
Step by step
- 1
Browse projects and join the Meridial network
Go to meridial.ai (the expert-network arm of Invisible Technologies), browse open opportunities on the projects page, and join the network. This is the entry point, not the invisibletech.ai corporate careers page.
- 2
Complete a detailed expert profile
Fill out your profile with your specific domain expertise (law, STEM, finance, coding, linguistics, AI safety, creative writing, etc.). Matching is expertise-driven, so a vague profile means fewer or no invitations. State your niche precisely.
- 3
Profile review and matching
Meridial reviews your expertise against current project needs. If there is a match they reach out with project details and next steps; if not, your profile stays active for future opportunities. Joining does not guarantee an engagement.
- 4
Pass the project assessment / screening
For most AI Data Trainer projects you complete a skills assessment (and sometimes an interview or evaluation) before you are cleared. Reviewers describe it as time-consuming (up to several hours) and focused on logical reasoning and following instructions exactly.
- 5
Get assigned to a project and start paid work
Once you pass, you are onboarded to a specific project or team and begin doing the work as a contractor. You only ever see projects matched to your profile, and project invitations spell out scope and fees before you accept.
Meridial Assessment (role-specific logic/reasoning evaluation)
Invisible vets you two ways. First, a profile review: after you join the Meridial network and complete your profile, the team reviews your stated expertise against current project needs and only reaches out if there is a match. Second, for many AI Data Trainer projects (especially generalist entry roles) you must pass a skills assessment before you are cleared to work. Independent test-prep guides describe it as an 'agentic reasoning' evaluation: it tests whether you can break a problem into logical steps, spot patterns, and follow instructions literally without adding outside assumptions. Reported sections include Critical Thinking (judging claims strictly from a provided passage), Word Logic, and Abstract/Diagrammatic Reasoning (shape/pattern sequences). Reviewers say the assessment is 'not always difficult, but time-consuming' and can take several hours. Important: Invisible does not publish the exact structure, and it varies by project, so the section list is reported-by-worker-guides (a single third-party test-prep site), not official.
Format
Online, unproctored, completed at your own pace after applying; reported to take up to several hours. Structure varies by project/role. Invisible agreed to acquire technical-assessment vendor WeCP (announced March 2026, integrating into Meridial), so expect a formal skills-testing step for technical roles.
How to prepare
- Answer ONLY from the text/data given. The single biggest rule reviewers stress: if the passage does not state it, treat it as unknown. Do not use outside knowledge or 'common sense' to fill gaps.
- Read instructions for each section carefully, the rules differ between sections, and follow them literally. This is itself what they are testing (instruction-following for AI training).
- For abstract/diagrammatic items, track one element at a time (shape, colour, angle, number/position) instead of trying to read the whole image at once.
- Budget several hours and do it when rested. It is long and error-checking heavy; rushing causes careless mistakes.
- Have your niche/domain clearly stated in your profile so you are matched to (and assessed for) work you actually know.
Why people get rejected
- Introducing outside knowledge or assumptions instead of reasoning strictly from the provided material.
- Not following the exact instructions of each section (the core skill being screened).
- Weak or imprecise written English (a stated expectation for the work).
- No profile-to-project match, so you are never invited to assess or work even if capable.
- Inconsistent quality or careless errors on the long, detail-heavy tasks.
There is no fixed timeline and it varies widely. Some people are invited and start within days; others wait weeks or longer for a matching project, because work is invitation-based, not on-demand. As a benchmark for the more formal AI Data Trainer roles, Glassdoor self-reports show an average of around 66 days from application to hire for the Advanced AI Data Trainer role (across 27 reported interviews). Plan for a slow, patience-heavy onboarding rather than instant access to tasks.
You are paid as an independent contractor, typically twice per month, usually at an hourly rate. Generalist review work is reported around $20/hour; specialist and leadership rates range higher and vary by project. Each project invitation states its scope and fees before you accept, so you know the rate up front. Joining the network is free and does not guarantee any paid engagement.
Tips to get accepted
- Apply through meridial.ai, not the invisibletech.ai corporate careers page. The Meridial expert network (projects + profile) is the actual door for AI training contract work; the main careers page lists full-time corporate/engineering jobs.
- Make your profile expertise specific and narrow. Matching is done against project needs, so 'finance' or 'competitive programming in Python' beats 'generalist'. A precise niche is what triggers an invitation.
- On the assessment, answer strictly from the material provided and never inject outside knowledge or assumptions. This literal, instruction-following discipline is the exact skill they are screening for, and adding 'what you know' is the most-cited way people fail.
- Set aside a few uninterrupted, well-rested hours for the assessment. It is long and detail-heavy rather than tricky, and most avoidable failures are careless errors from rushing.
- Treat it as supplemental, invitation-based income and keep your profile active while you wait. Work comes in project waves, so a quiet period is normal and not a rejection.
What isn't public
- Invisible/Meridial does not publicly publish the exact assessment structure (section names, question counts, time limits, or pass mark). The section breakdown (Critical Thinking / Word Logic / Abstract Reasoning) comes from a single third-party test-prep guide (aitrainer.work) and worker reports, not from Invisible's own documentation, and it likely differs by project.
- The official Meridial FAQ does NOT state a fee policy either way; the 'no joining fee' point is inferred from how worker-side expert networks generally operate, not confirmed by official documentation.
- Precise per-country eligibility is not published. The official projects page shows only remote, profile/language/location-matched projects (a Caribbean-English project was the only one visible at check time). Any specific country list (e.g. US/UK/India/Egypt/South Africa) is NOT confirmed by Meridial's own pages.
- There is no official published timeline from application to first paid task. The ~66-day figure is a Glassdoor self-report average for the Advanced AI Data Trainer role only, not a company statement, and other trainer levels report much shorter averages (AI Trainer ~16 days).
- Invisible does not publish official rejection reasons or acceptance rates. The failure reasons listed are inferred from reviewer and candidate reports.
- Exact pay rates per project are not disclosed publicly; the ~$20/hr generalist figure is from third-party reviews and rates are only revealed inside each project invitation.
- We found no substantial first-hand Reddit thread corroboration in this pass; corroboration rests on the official Meridial site plus independent review sites and Glassdoor self-reports.

Applying to Invisible: questions
How do I actually get accepted onto Invisible / Meridial?
Join the Meridial network at meridial.ai and complete a detailed expertise profile. Their team reviews it against current project needs; if you match, they invite you to a screening/assessment, and passing it gets you onto a specific project. There is no instant self-serve task access, acceptance is match-then-assess.
What is the Invisible assessment and how do I pass it?
It is a skills/reasoning assessment (reported to take up to several hours) that checks whether you can reason step-by-step and follow instructions exactly. The winning approach is to answer only from the information given, never from outside knowledge, and to read each section's rules carefully since they differ. It rewards careful, literal accuracy over speed.
Why do people get rejected?
The most common reasons are adding outside assumptions instead of reasoning strictly from the provided material, not following the exact task instructions, weak written English, or simply having no profile that matches an open project so you are never invited. Careless errors on the long tasks also sink otherwise-capable applicants.
How long until I get my first paid task?
It varies a lot. Some start within days of matching; many wait weeks or longer because work is invitation-based. For the Advanced AI Data Trainer role, Glassdoor self-reports show roughly a two-month average from applying to being hired, though other trainer levels report shorter. Keep your profile active and expect a patient onboarding.
Is it free to join, and how do I get paid?
There is no application fee to join the Meridial network (though Meridial's FAQ does not spell out a fee policy explicitly). You work as an independent contractor and are typically paid twice per month, usually hourly, with each project's rate disclosed in the invitation before you accept. Joining does not guarantee any paid work.
How long does it take to hear back from Invisible?
There is no fixed timeline and it varies widely. Some people are invited and start within days; others wait weeks or longer for a matching project, because work is invitation-based, not on-demand. As a benchmark for the more formal AI Data Trainer roles, Glassdoor self-reports show an average of around 66 days from application to hire for the Advanced AI Data Trainer role (across 27 reported interviews). Plan for a slow, patience-heavy onboarding rather than instant access to tasks.
Does Invisible have an assessment?
Yes: Meridial Assessment (role-specific logic/reasoning evaluation). Invisible vets you two ways. First, a profile review: after you join the Meridial network and complete your profile, the team reviews your stated expertise against current project needs and only reaches out if there is a match. Second, for many AI Data Trainer projects (especially generalist entry roles) you must pass a skills assessment before you are cleared to work. Independent test-prep guides describe it as an 'agentic reasoning' evaluation: it tests whether you can break a problem into logical steps, spot patterns, and follow instructions literally without adding outside assumptions. Reported sections include Critical Thinking (judging claims strictly from a provided passage), Word Logic, and Abstract/Diagrammatic Reasoning (shape/pattern sequences). Reviewers say the assessment is 'not always difficult, but time-consuming' and can take several hours. Important: Invisible does not publish the exact structure, and it varies by project, so the section list is reported-by-worker-guides (a single third-party test-prep site), not official.
