Supersymmetry (SUSY) provides elegant solutions to several problems in the Standard Model, and searches for SUSY particles are an important component of the LHC physics program. This paper presents the latest results from SUSY searches conducted by the ATLAS and CMS experiments with the Run 2 dataset. These searches target multiple final states and different assumptions about the decay mode of the produced SUSY particles, including searches for both $R$-parity conserving models and $R$-parity violating models and their possible connections with the recent observation of the flavour and muon $g-2$ anomalies. The paper also covers recent CMS and ATLAS SUSY searches for long-lived particles, targeting either the long-lived particle itself or its decay products at a significant distance from the collision point. These signatures provide interesting technical challenges due to their special reconstruction requirements as well as their unusual backgrounds.
