GLG Intern interview questions

over the phone interview, then 1-2 hour interview on-site where talk to several employee/managers. Language intern -parts of interview conducted in those languages. Difficult to know what they were looking for. Polite, friendly and enthusiastic interview style- which is very misleading as got impression interview was going very well. Language parts done with peer employees- difficult to know if interested in just language skills/ ability to work well with people or actual qualifications
