Getting to know the office space, production facilities, restaurant / canteen, etc. No matter how stress-resistant or extravert an individual might be, any change brings stress. Let him/her come to the new office and feel like he/she has already been here before. Build a VR tour around your office and/or production facilities. Give your new hire the details and hints only you, and the Team know (where the cups, plates and napkins are, where the sunny side of the office is, where the air conditioner if it is blowing too much, where you can hide away to have some rest during the day break, where it feels most comfortable to work, where the best business lunches are, etc.).
