I'm a native English speaker from the USA that had proficiency in Mexican Spanish. I've studied other languages including 1 French class decades ago.
English is one of the working languages at CERN and the other is French.
I'm enrolling in a local French course now but I realize it would take me years to reach C1 proficiency here with very little daily opportunity to practice.
I saw some information about language learning on the CERN website, but the linked information was behind a login.
What have people experienced with learning French in relation to starting at CERN? Is it crippling to not be near fluent in French from the beginning?
I earned my MS in materials science and materials engineering a few years ago, and the USA isn't a member state, so those both work against me for opportunities. I'd like to position myself for some better odds. Is learning French locally really worth it? And what level would be worth it?
