Abstract: The Run 2 operation of the Large Hadron Collider allowed the ATLAS and CMS experiments to record up to 4 fb-1 of proton proton collision data at a centre-of-mass energy of 13 TeV. A summary of the recent results of searches for supersymmetry is presented. Several analyses are reported using complementary final states, mainly targeting the strong production of squarks and gluinos. In addition to reviewing some of the techniques that made the analyses possible, a perspective on the future will be given.
