Linguist roles in AI data work include translating and reviewing specialist content, post-editing machine translation and judging translation quality for model training. Some postings in this group say a translation test or a quality test comes before any work. These practice questions focus on accuracy, terminology and how you justify edits.

Practice questions

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

  1. Post-edit this machine translation and explain your changes.

    A good answer covers: Fix meaning errors first, then terminology, grammar and style. Keep edits minimal where the output is already correct, and say why each change was needed.

  2. What is the difference between light and full post-editing?

    A good answer covers: Light post-editing makes the text understandable and accurate; full post-editing brings it to publishable human quality, including style and consistency.

  3. How do you handle a term that has no agreed translation in your target language?

    A good answer covers: Check client glossaries and term bases first, then authoritative sources; propose a term, keep it consistent and flag it in a query.

  4. You are given two translations of the same sentence. Which is better, and why?

    A good answer covers: Pick one and justify it with specific criteria: accuracy, completeness, terminology, fluency and register. Point to the exact words.

  5. Which CAT tools have you used, and how do translation memories help quality?

    A good answer covers: Name the tools honestly (for example a CAT tool listed in the posting) and explain that memories and term bases keep repeated segments and terms consistent.

  6. How do you translate patent or legal text differently from marketing text?

    A good answer covers: Patent and legal text needs literal precision, consistent terms and no added meaning; marketing text allows adaptation for the reader. Give an example.

  7. What would you do if the source text contains an error?

    A good answer covers: Translate faithfully, do not silently fix meaning, and raise a query or note to the project manager.

  8. Explain a false friend between your two languages.

    A good answer covers: A word that looks similar but means something else, with both meanings and an example of the error it causes.

  9. How do you keep consistency across a long document?

    A good answer covers: Glossary, translation memory, a style guide, a final consistency check of key terms and numbers.

  10. Write a short justification for choosing one translation over another, as a rater would.

    A good answer covers: Two or three sentences that name the criterion, quote the problem and state the effect on a reader.

What the platforms say about the assessment

In the 9 October 2026 data, roles in this group came from Welo Data (Welocalize), RWS TrainAI, Meridial, micro1 and Appen. 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.

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.

RWS TrainAI

  • Some RWS TrainAI postings say you must pass training modules and a required test created by the client before starting work.
  • Other postings mention language knowledge assessments, an evaluation test to complete within 48 hours of receiving it, and onboarding and calibration sessions.

Meridial

  • Meridial postings describe the work and requirements but do not describe the screening steps.
  • Postings say contractors supply their own secure computer and internet connection, and recording roles add a high-quality microphone and recording setup. Company benefits such as health insurance do not apply.
  • We could not confirm Meridial's selection steps from a public page; treat the posting itself as the guide.

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.

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.

Adapting content to a specific language and culture, including units, dates, idioms and references, not just translating words.

Post-editing

Correcting machine-translated text so it reads accurately and naturally.

Locale

A specific language and region combination, such as Spanish for Mexico or Portuguese for Brazil. Many language roles are tied to one locale.

Native proficiency

Command of a language at the level of someone who grew up speaking it, which many language roles require.
