Workload: ~15h/week
Engagement: Project-based

Field: Languages

Evaluate, edit and annotate Portuguese text used to assess and improve large language models. The work covers translation, summarization, dialogue, grammar correction and culturally appropriate language use.

The work

You will review Portuguese output from a large language model for accuracy, fluency and contextual fit. Day-to-day tasks may include assessing translations and summaries, correcting dialogue or grammar, rewriting unnatural passages, and annotating grammatical, syntactic and semantic features.

What the screening emphasizes

Mercor is looking for native or near-native fluency in Portuguese, supported by professional experience in translation, editing, linguistic annotation or NLP data work. Screening is likely to test whether you can identify subtle errors, distinguish acceptable variation from genuine defects, account for regional usage, and explain model failures with precise evidence rather than preference alone.

Working arrangements

The project is presented as work within a distributed, remote-team setting, with feedback shared with AI researchers. The listing does not specify whether the workflow is fully asynchronous or state typical weekly hours, so candidates should be ready to clarify scheduling, workload and turnaround expectations during onboarding.

Interview prep — 10 questions

Matched to what this platform's screening actually measures. Answer each out loud in 60–90 seconds: claim → concrete example → implication.

What it tests: This establishes whether your Portuguese expertise comes from verifiable production work and whether that work overlaps with the project's evaluation and annotation tasks.
A strong answer: Give specific roles or projects, the Portuguese content involved, your responsibilities, and the quality standards or guidelines you followed. Distinguish clearly between translation, editing, annotation and model-evaluation experience.
Where people lose it: Candidates lose points by describing general fluency or academic study without identifying professional deliverables they personally produced or reviewed.
