Best way of becoming a German translator
I am of German nationality and have learned German as part of the curriculum in Germany.
However, I have always worked in international companies. I have lived in the UK since 2005. Now with the pandemic, I would like to re-invent myself to get up to speed to confidently and professionally offer German/English translation service, but would probably need to brush up on my professional German.
I would like to receive some recommendations on the best and most efficient way to go about it.
