The focus of our project is the deepening and application of the learned languages in the field of business behaviour. This includes, among other things, the focus on applications, curriculum vitae, job interviews and marketing activities. These areas are implemented by using various new forms of communication, e.g. presentation tools, live chats and video conferences. Furthermore, the eTwinning portal will serve as a communication and documentation platform for our Erasmus+ project "Language Switching and International Business Behaviour".
