In the Standard Model of Particle Physics (SM), 2 $\rightarrow$ 2 processes are described well by Quantum Chromodynamics. Any departure from SM expectations implies the existence of New Physics (NP). We present the search for NP in dijet final states in both high mass and low mass regimes. The use of novel jet substructure techniques to probe very low values of the dijet mass are discussed. The search for new physics in four-jet final states is presented. The search for microscopic black holes in energetic multijet final states is shown. Finally, a search for NP with heavy flavor jets is included. These analyses utilize between 2.3 to 15.7 fb$^{-1}$ of data collected at $\sqrt{s}$ = 13 TeV using the ATLAS and the CMS detectors at the Large Hadron Collider at CERN. In the absence of a significant excess of events in data, a wide variety of signal models are excluded. These results represent the most stringent limits on NP scenarios in jet-based final states.
