Purpose“Know thyself” helps one to decide the career goal of his/her life and enables one to become self-concordant. In this context, the present work aims to discern the childhood interests (CI) of the HR professionals vis-à-vis their relevance.Design/methodology/approachThe current study is grounded on two theoretical perspectives such as Socio-Cognitive Career Theory (SCCT) and Holland Theory of Career Choice (HTCC). In this regard, a mixed methodology has been applied. The research has been carried out in two phases. In the first phase, a focused group of experienced HR professionals was interviewed to understand their CI and their relevance to the HR profession through a qualitative analysis method such as narrative analysis. In the second phase, an Intuitionistic Fuzzy Number-based Full Consistency Method (FUCOM) is applied to find out the dominant CI based on the ratings given by 423 Indian HR professionals.FindingsAll professionals agreed that their CI have helped them perform in their profession. The research identifies five themes or main attributes of personality: Creative (Aesthetic-Non Verbal/Cultural), Communicative (Verbal/ Expressive Activities), People friendliness (Social Contribution), Socially Inclusive (Sociological leadership interest) and Physical Activity (Kinesthetic interests) with 24 subattributes (i.e. childhood interests). It is found that intrinsic interests in societal contributions have been a dominant feature since the childhood days of HR professionals. In all cases, FUCOM shows a very small DFC value <0.00005.Practical implicationsThe research provides an important direction to the decision-makers for policy making and aspiring professionals an essential impetus to career planning.Originality/valueThis study is a rare one to discern CI using a mixed methodology for Indian HR professionals.
