After getting calls from different IIMs, I was not sure abiut what kind of preparation is needed for GDPI process. One of friend suggested me to join Backspace for concrete GDPI preparation.
I remember my first mock interview where I wasn't able to answer basic questions. With proper guidance from mentors through different b-schools based mock interviews and deep analysis of every aspect of interviews, i was well prepared for GDPI process.
I will always be thankful to backspace for mentoring me and helping me secure admission offer from my dream B-school.
