Common questions
Do task-based AI training roles require an interview?
Most skip a live interview entirely and gate access through an automated assessment or qualification task instead. Where we've confirmed the specific requirement for this listing, it's called out above in What We Know About This Role.
What does task-based AI training work look like?
Practical, hands-on data work: recording short videos, categorizing images, rating text responses, or analyzing data. Tasks are designed to be short and distinct, typically 5 to 60 minutes each.
What does Data Science work look like for a Speech AI Evaluation Specialist - Portuguese (Brazil)?
Tasks here are scoped to Data Science, not generic labeling. As a Speech AI Evaluation Specialist - Portuguese (Brazil), expect to draw on real domain judgment (evaluating outputs, correcting errors, or providing expert reasoning specific to Data Science) rather than following a one-size-fits-all rubric. If you don't have hands-on Data Science background, this is likely not the right listing to start with.
What specific skills does this listing call for?
English and Portuguese are named directly in the listing. If you don't have hands-on experience with these, expect the screening process to test for them directly rather than accepting adjacent experience as a substitute.
How much does this specific role pay?
This listing is posted at $6/hr, an hourly rate. Pay can change between when we last checked the listing and when you apply, so confirm the current number on the platform's own application page before committing time.
Do I need to be fluent in English or Portuguese?
Yes. This role specifically requires English or Portuguese proficiency, on top of the English most AI training work assumes by default. If English is not a language you're fluent in, this is not the right role. Filter for your native language to find better-matched listings.
Can I apply from outside Rio de Janeiro or Brazil?
This specific role is open only to people based in Rio de Janeiro and Brazil. If you are somewhere else, applying is unlikely to lead to an offer even if you pass the assessment, because the restriction is usually about where the work can legally be contracted rather than your skills. Read the full description for any tax-residency or right-to-work caveats before you apply, since they can differ by country.
