IBM Senior Strategy Consultant interview questions

I was an Off Campus Hire, Total selection process involved 1 GD, 3 Interviews. Total 4 rounds . I will give round wise feedback - Please mark a point here in Walk In drive there were around 60 participants from IIM's, ISB and IIT . I was from IIT and college wise in lowest bracket. 1st round was GD round (which was a cake walk for me at least) . Love Marriage vs Arrange Marriage - just to screen out few people (as few freshers also attended the drive). 2nd Round was - Interview : It was take by a person above 1 post senior to me - again a normal pass through round all candidates were sent for 2nd round. 3rd Round - IT was taken by Senior Managing Consultant - Fully technical round , lasted for 60 mins on phone (con call Noida to Bangalore office). 75% people were rejected in this round 4th Round - Partner Round : It was more of a HR round (atleast I thought so) , questions like how u will treat your peers, why you want a job change (i was already campus selected for another firm), etc. Overall result - Selected - Conversion rate (5/60) -- Only 5 people were given offer.
