Do these people get same preference as IIT/IIM people in india

I have a question which was popping since long in my mind , there are many people who go for higher studies abroad in b-schools like LBS INSEAD HEC PARIS, or ivy league at USA or some for MS CS in good colleges , After working for few years with careful financial planning and saving many of them come back to India as they have old age parents, friends and family here . Do these b-schools people get same preference as someone from IIM BLACKIS/FMS/ISB OR as someone from IITs/Nits for higher positions based on performance or in other general things, if they are continuing job here rather going for some business/startups???
