We explore possible signatures of the interaction between dark matter and massive neutrinos in the upcoming post-reionization and galaxy surveys: Square Kilometre Array (SKA1 and SKA2) and Euclid. All these missions show promise in constraining the interaction parameter and total neutrino mass by a few orders compared to the existing constraints from Planck telescope, SKA2 performing the best among them. We further perform a brief investigation of the prospects of some of the next generation Cosmic Microwave Background (CMB) missions in combinations with LSS experiments in improving the constraints. Our analysis reveals that both SKA2 and CMB-S4 + Euclid + SKA1 IM2 combination will put the strongest bounds on the model parameters.
