Languages Brazilians use in job interviews

An article here in Portuguese references a study by a job posting site on when Brazilians end up doing job interviews in other languages and which languages they are when they do:

A survey done by Catho Online, a company that publishes resumes and job openings on the internet, indicates that 5.3% of Brazilians have had a job interview in another language in the selection process for their current job. Of these, 80% were done in English, 13% in Spanish and 7% in other languages.
