The subject of this study is interview as a genre of modern English business discourse as it visibly demonstrates the linguo-pragmatic characteristics of business communication. The communicative goal fully defines the communication strategy, which is expressed in the choice of the conversation manner, the form and the content of the message. Thus, the objective of this study is to teach business students specific linguistic phenomena from the viewpoint of functional pragmatics. An interrogation belongs to the main communicative sentence types. Its main characteristic is focus on getting information. Tag questions are a sub-paradigm of the interrogation category, organizers of verbal interaction and, therefore, stimulators of communication in the modern English language. A recent tendency in various languages has shown a convergence of the conversational and the official styles expressed in the simplification of grammar forms and the use of dialogical cliches as well as in the use of certain words and expressions typical of the oral conversational style. That is why such common and stereotyped conversational expressions as tag questions have become popular in modern business English.
