The invention pertains to a process for the hydroprocessing of a hydrocarbon feedstock wherein said feedstock is contacted at hydroprocessing conditions with a catalyst composition which comprises bulk catalyst particles which comprise at least one Group VIII non-noble metal and at least two Group VIB metals. The Group VIII and Group VIB metals comprise from about 50 wt. % to about 100 wt. %, calculated as oxides, of the total weight of the bulk catalyst particles. The metals are present in the catalyst composition in their oxidic and/or sulfidic state. The catalyst composition has an X-ray diffraction pattern in which the characteristic full width at half maximum does not exceed 2.5° when the Group VIB metals are molybdenum, tungsten, and, optionally, chromium, or does not exceed 4.0° when the Group VIB metals are molybdenum and chromium or tungsten and chromium.
