I'm enrolled in a research master's degree in Energy (1st year completed) in a target school (Ecole des mines de paris). I'm currently doing my gap year, first 6 months in financial audit (big 4) and second one in transaction services in another big 4.
I'm particularly interested in strategic consultancy in MBB, thus i applied to different business schools.
I have been accepted in essec's mim (2 year grande ecole) and Msc DSBA and in HEC's Msc strategic management.
My question is : which one of the previously cited programs offers me the most chances to pass the screening phase of MBB recruitment. I'm not sure if the 2 year grande ecole program is better perceived than the 1 year Msc.
Please note that i'm not following the grande ecole program of Ecole des mines.
Edit: i'm interested in offices located in France, UK and the middle east.
