You don't have a hundred rubles, but you have a hundred useful contacts. Sometimes one acquaintance can be the start of an interesting project, help you find a job, or open new opportunities for professional growth. At such a moment it is important not only to exchange contacts, but also to learn how to build relationships that will benefit both parties. Together with the "Professional Development" project, we compiled six rules on cards that will help you make a professional introduction and maintain communication after the first meeting.
