Particle interferometry has proven to be an indispensable tool in probing the space-time evolution of femtoscopic collision systems. In this talk, I show how hydrodynamic predictions for the space-time evolution of high-multiplicity $pp$ and $p+$Pb collisions can be tested against interferometric observables designed to probe their size and shape. In particular, I consider how the dependence of these observables on the transverse momentum $K_T$ and the multiplicity $dN^{\mathrm{ch}}/d\eta$ may reflect the hydrodynamic nature of the evolving system.
