At Interactive Brokers, we are always looking for bilingual skills from our staff to better suit and expand our client base. Do you speak any other languages fluently?

This is a straightforward question where your interviewer is looking to simply see if you could the additional skill of being bilingual to the team at Interactive Brokers. If you are, it could be potentially highly marketable to new clients. If being bilingual is required for the job, you would likely see those details in the job advertisement. Feel free to speak openly and honestly for this question and an answer of no for this question shouldn't disqualify you from candidacy for the position if it is not a requirement.
