  "abstract": "Interacting supernovae (SNe) IIn and Ibn show narrow emission lines and have always been a mysterious and unsolved genre in SNe physics. We present a comprehensive analysis of the temporal and spectroscopic behaviour of a group of interacting SNe~IIn and Ibn. We choose SNe~2012ab, 2020cui, 2020rc and 2019uo as representative members of these SN sub-types to probe the nature of explosion. Our study reveals that SNe~IIn are heterogeneous, bright depicting multi-staged temporal evolution while SNe~Ibn are moreover homogeneous, comparatively fainter than SNe~IIn and short lived, but limited in sample to firmly constrain the homogeneity. The spectroscopic features display a great diversity in H$\\alpha$ and He profiles for both SNe~IIn and Ibn. The representative SN~Ibn also show flash ionisation signatures of CIII and NIII. Modelling of H$\\alpha$ reveals that SNe~IIn have in general an asymmetric CSM which interacts with SN ejecta resulting in diversity in H$\\alpha$ profiles.",
