Importance of Languages

Nowadays, knowing many languages is a huge advantage especially for job applicants. There are millions of people out there who are able to talk more than two languages. That is impressive, isn't it? How many languages do you know? Do you have any certificates?
Personally, I do know many languages and I have several certificates. I have C2 in English and Sorbonne C2 in French. In university, I tried to learn some Spanish and I succeeded to pass the exams for B2 Level. As a Recruiter, I think that languages do play a very important role. I would never hire someone who does not know English and French or German. These languages are essential, aren't they?
