To ensure comprehensive support, your host organisation will assign you a mentor. This person does not work in your immediate working environment, which means they are impartial and are not your manager. Your mentor will live locally, be easy for you to contact and will help familiarise you with your new surroundings.
In addition, there will be a designated contact for you at your place of assignment who will show and explain everything to you. They will help you, especially at the beginning, with any questions you have about your place of assignment.
