MicroBooNE is a 100-ton scale liquid-argon time projection chamber (LArTPC) neutrino experiment located on the Booster neutrino beamline at Fermilab. The experiment first started collecting neutrino data in October 2015. The detector, the first in the short-baseline neutrino program at Fermilab, is the longest operating LArTPC to date and plays an important role in a phased program towards the construction of massive kiloton scale detectors for future long-baseline neutrino physics (DUNE). We present results on the performance of the detector after three years of data-taking, highlighting operational accomplishments such as the high electron lifetime and signal-to-noise levels achieved. Additionally, we describe the current state of MicroBooNE reconstruction, presenting results which show the detector's ability to perform sub-millimeter tracking and produce accurate momentum and calorimetric measurements capable of enabling the analyses needed to explore the exciting neutrino interaction physics this detector was built for.
