HR managers always bear a great responsibility for selecting personnel; it is essential not to make mistakes with future colleagues, as this can lead to some problems for the company. In the situation that arose, the specialist could not draw the correct conclusions about the future employee; it turned out that his true goal was to enter the organization to damage its reputation. By evaluating only the information received verbally, the manager did not get the whole picture of the person being hired, which led to irrevocable consequences for the company. Non-verbal signals play a vital role in business communication since it is crucial for the interlocutors to establish contact, reach a mutual understanding, or determine the speaker’s true intentions. Nonverbal indicators provide individuals in a professional setting to interpret non-verbal cues to adapt their communication tactics to achieve their goals. It may seem that non-verbal means are not as necessary as verbal ones. However, studies have shown that in communication, on average, up to 55% of information from the interlocutor an individual receives precisely through non-verbal means (posture, facial expressions, gestures) (Eaves & Leathers, 2017). Usually, 38% of the perceived information falls on sound means (tone of voice, intonation of speech), and only 7% from general information through verbal means (Eaves & Leathers, 2017). Through the verbal channel, mainly pure information is transmitted; the non-verbal channel represents the attitude both to the communication partner and the transmitted information. Especially in professional settings, a person can express a position with which they do not agree to achieve specific goals while non-verbally transmitting disagreement. The ability to read implicit signs is an important skill when interacting with opponents or colleagues, which will allow getting more information from any conversation. The correspondence of a person’s verbal message to their actual desires, values, and beliefs, which are manifested non-verbally, is determined as communicative congruence. The human subconscious mind notices the discrepancy between the meaning of the interlocutor’s words and how they were pronounced (intonation, tempo, volume, etc.) and what non-verbal accompaniment they had (posture, gestures, facial expressions, etc.). Although consciousness is mainly focused on the meaning of words, the subconscious mind can make its verdict – distrust. As a result, a person experiences conflicting feelings, not knowing which messages to believe (verbal or non-verbal), which leads to confusion and discomfort. In these situations, it is recommended to better trust the information transmitted by the interlocutor’s body since this is a more reliable source of information (Vrij et al., 2019). In professional communication, to more accurately navigate the situation, it is necessary to notice and understand non-verbal messages emanating from the communication partner and control the messages sent to the partner. In the analysis, scientists propose the following classification of non-verbal indicators:   * distance (i.e., proxemics)   * body language / movements (i.e., kinesics)   * touch (i.e., haptics)   * app
