Quote ="Standee"one thing to remember though, most EU citizens speak and write English to a good standard (it could be argued, better than many posting on here)and yet few "English" people have more than a "conversational" second language.'"
I worked in Madrid for nearly a year and picked up the language for use outside of the office quite quickly.
Granted, the project's official language was English but my Spanish colleagues knew that I was keen to use Spanish wherever possible. Nonetheless I'm certain my grasp of the language would have accelerated if I'd had to use Spanish more in the office.
Ditto with working in Germany.
So, your point is accurate, I couldn't have started on a Spanish-speaking job without better Spanish language skills and I actually failed a German interview for another job there where the project language was German as it was too hard work (quite understandably) for the interviewer to simplify his German for me.
If I'd been better prepared, I reckon I'd have stood a really good chance of that job as I was very experienced in all the other skills required, indeed the guy was in a bit of a dilemma whether to give me the job despite the language shortfall but, to be honest, I'd have struggled with the scoping and planning meetings early in the project.
It's not actually difficult to learn another language but if you don't know (as I did but many don't) what a verb is or a noun, even in English, you're going to have to learn that at the same time, which makes progress that much slower.
On the other hand, a large part of the rest of the world tends to use English as a sort of Esperanto second language, which does make us a little lazy.
