Robotics roles range from operating or teleoperating robots and recording demonstrations, to filming everyday tasks from a first-person view, to engineers who judge robot data and pipelines. Several postings stress fine motor skills, steady recording and following precise task scripts. These practice questions help you prepare.

Practice questions

These are practice questions written for this site to help you prepare. No platform has said it asks these exact questions.

  1. How would you demonstrate a task so a robot can learn it from video?

    A good answer covers: Slow, consistent movements, hands and objects visible, one task at a time, and the same start and end positions.

  2. What is teleoperation, and what makes a good teleoperator?

    A good answer covers: Controlling a robot remotely; good operators are precise, patient and follow safety rules.

  3. A recorded demonstration has a mistake halfway. What do you do?

    A good answer covers: Follow the project rule, usually discard and re-record rather than continuing.

  4. How would you annotate a robot manipulation video?

    A good answer covers: Mark each action's start and end, the object and the outcome, using the taxonomy given.

  5. What safety checks matter around a physical robot?

    A good answer covers: Clear workspace, emergency stop within reach, knowing the robot's range of motion.

  6. Explain the gap between simulation and the real world in robotics.

    A good answer covers: Simulated physics, sensors and visuals differ from reality, so behaviour learned in simulation may fail on real robots.

  7. Describe a hands-on task you do with high precision.

    A good answer covers: A concrete example showing fine motor control and patience.

  8. How do you stay consistent across many repeated recordings?

    A good answer covers: Same setup, lighting, camera position and pace, with checks between takes.

What the platforms say about the assessment

In the 9 October 2026 data, roles in this group came from micro1, Welo Data (Welocalize), Terac, Appen and Innodata. Each platform runs its own process, and steps can differ by role. Below is what each platform's public pages or postings say, followed by lines quoted from current postings in this group.

micro1

  • micro1's experts page describes four steps: apply for opportunities, take the AI interview, get onboarded, start earning.
  • Postings commonly list screening questions, then an AI interview, then in some roles a technical assessment, then a review by the hiring manager. Interview lengths stated in postings range from about 10 to 30 minutes.
  • Some postings ask you to complete the interview and assessment without outside assistance.
  • micro1's FAQ says certification does not guarantee immediate placement on a project.

Welo Data (Welocalize)

  • Welo Data's join page lists these steps: apply, create a Welo Works account, take a Language and Cultural Assessment, optional study materials, a qualification exam, then payment setup and agreement.
  • Many postings say there is no formal interview and the process is automated. Several mention learning modules and a quality test designed by the client; translation roles may include a translation test.
  • Welo Data says it only contacts applicants from @welocalize.com, @weloglobal.com, @hire.lever.co and @welodata.ai addresses and never asks for fees.

Terac

  • Terac's expert docs describe signing in with LinkedIn, verifying your phone, connecting LinkedIn or adding a resume, and a short voice conversation of about 10 minutes that the docs say you can skip and take later.
  • Each opportunity then has its own steps, usually screening questions followed by the tasks themselves. Research postings describe remote video or voice interviews of 30 to 90 minutes.

Appen

  • Appen's postings list requirements (for example age 18 or older, a compatible phone or the Appen Mobile app, a quiet room, and the language set in your profile) but do not name a specific test.
  • We could not confirm Appen's screening steps from a public page; treat the posting itself as the guide.

Innodata

  • Innodata postings describe the work and the hourly range but do not describe the screening steps.
  • Postings state that Innodata will never ask for payment, banking details or sensitive personal information during the application process.

Steps were read from public pages and postings, not tested first-hand. Passing a screening does not guarantee a project, hours or pay.

Terms to know

Data collection

Projects where you create new data, such as photos, videos, recordings or written samples, instead of judging existing data.

Annotation

Adding labels or notes to data such as text, images, audio or video so a model can learn from it.

Domain expert

Someone hired for professional knowledge in a field, such as law, medicine or engineering, to write or judge expert-level tasks.

Model evaluation

Testing how well a model performs on a set of tasks, often by people scoring answers against a rubric.
