Sample interview questions
How would you handle an audio clip where the spoken words are difficult to understand?

I would replay the clip carefully, follow the project style guide for uncertain speech, and flag the segment for adjudication when the audio remains ambiguous rather than making an unsupported assumption.

What steps would you take to ensure accurate word-level timestamps?

I would listen closely around each word boundary, compare the alignment with the audible speech, make precise adjustments, and conduct a final review before submitting the batch.

How do you maintain consistency during repetitive annotation tasks?

I use the style guide as a reference, apply the same decision rules throughout the batch, and periodically review earlier work to confirm that my annotations remain consistent.

What experience or strengths would help you succeed in transcription and data-labeling work?

Strong listening comprehension, native-level familiarity with Brazilian Portuguese, attention to detail, and patience with structured quality-control tasks are essential strengths for this type of work.

How would you organize 15 to 20 hours of freelance work each week?

I would schedule focused work blocks in a quiet environment, track completed batches and quality checks, and leave time for reviewing flagged items or addressing project feedback.
