A hydrocarbonaceous feedstock is hydrocracked by contacting the feedstock in a first reaction stage at elevated temperature and pressure in the presence of hydrogen with a first hydrocracking catalyst to obtain a first effluent, separating from the first effluent a gaseous phase and a liquid phase at substantially the same temperature and pressure as prevailing in the first reaction stage, contacting the liquid phase of the first effluent in a second reaction stage at elevated temperature and pressure in the presence of hydrogen and a second hydrocracking catalyst to obtain a second effluent, obtaining at least one distillate fraction and a residual fraction from the combination of the gaseous phase and the second effluent by fractionation, and recycling at least a part of the residual fraction to a reaction stage.
