Learning a foreign language also means knowing how to take the plunge!
And quick results are bound to surprise you and your colleagues even more.
Only one week, eight hours a day (including the lunch break in the target language!), will enable you acquire a proficiency level, which will allow you to communicate effectively and confidently.
It is the ideal option in case of an immediate expatriation or where linguistic proficiency is needed urgently.
It is also an opportunity to improve your skills further, during a quieter professional period (for example during vacation time).
