Boston Consulting Group Research Associate interview questions

The interview had a body language expert sitting in the corner observing, as well as two interviewers. Also, this position required me to speak Spanish. I had already passed a written Spanish test before being invited to interview and I thought the language part of the assessment was complete. One of the interviewers was Spanish and part of the interview took place in Spanish, which was unexpected! I had to answer some standard interview questions and then research and put together a powerpoint on a topic suggested by them in I think 20 minutes.

Received an email from BCG recruiter about a position. I was then asked to send my CV. An initial call about myself, background and how do I fit in BCG. Asking about my past experience and what I am looking at the moment.
