I will report about recent progress on simulating long-time evolution of neutrino-driven core-collapse supernovae in three dimensions. These simulations cover the shock revival phase and the propagation of the SN shockwave through the envelope of the exploding star. The results demonstrate that large-scale asymmetries in the metal-rich ejecta after the shock break-out still carry information of the early-time asymmetries created during the explosion phase, despite being modified by fragmentation due to Rayleigh-Taylor instabilities. Our results also show that the stellar structure, which determine the growth rate of Rayleigh-Taylor instabilities at composition interfaces and thus the efficiency of outward mixing of metals and inward mixing of hydrogen after the passage of SN shock, play an important role in shaping the morphology of the ejecta at late times. Therefore, studies of global asymmetries of the ejecta and mixing might offer some insights on the structure of the progenitor star.
