In this article we investigate the prospects of searching for sterileneutrinos in lowscale seesaw scenarios via the lepton flavour violating (butlepton number conserving) dilepton dijet signature. In our study, we focus onthe final state $e^\pm \mu^\mp jj$ at the HL-LHC and the FCC-hh (or the SppC).We perform a multivariate analysis at the detector level including the dominantSM backgrounds from di-top, di-boson, and tri-boson. Under the assumption ofthe active-sterile neutrino mixings $|V_{ l N}|^2=|\theta_e|^2=|\theta_\mu|^2$and $|V_{ \tau N}|^2 = |\theta_\tau|^2=0$, the sensitivities on the signalproduction cross section times branching ratio $\sigma(p p \to l^\pm N)\times{\rm BR} (N \to l^{ \mp} jj)$ and on $|V_{ l N}|^2$ for sterile neutrino mass$M_N$ between 200 and 1000 GeV are derived. For the benchmark $M_N=500$ GeV,when ignoring systematic uncertainties at the HL-LHC (FCC-hh/SppC) with 3 (20)${\rm ab}^{-1}$ luminosity, the resulting 2-$\sigma$ limits on $|V_{ l N}|^2$are $4.9\times 10^{-3}$ ($7.0\times 10^{-5}$), while the 2 -$\sigma$ limit on$\sigma \times {\rm BR}$ are $4.4\times10^{-2}$ ($1.6\times10^{-2}$) fb,respectively. The effect of the systematic uncertainty is also studied andfound to be important for sterile neutrinos with smaller masses. We alsocomment on searches with $\tau^\pm \mu^\mp jj$ and $\tau^\pm e^\mp jj$ finalstates.
