You should get going immediately, as b-schools give very less time to prepare for interviews (not more than 10-12 days). You can get interview preparation tips and interview experiences on http://www.general-ed.com/mba-interview-preparation
. As interviews constitutes important element in b-schools admission, I would suggest you to prepare well on questions like: professional achievements, leadership skills and other aptitudes.
Feel free to post any other concerns you might have.
I have applied for 4 schools in round 2 and confident of interview calls from atleast 2. I wanted to know what is the normal suggested timeline for interview preparation? Does it make sense to start after getting a call? Any info how other qualified candidates prepare will be very useful!
