Hi,
Regarding ur queries ..
There is one placement report on IE website but its for 2004. I recently received the latest Placement report for IE but I m not sure if that was bcos I have already paid the fees. You can request the adcom for a copy of placement report
I saw a mix of big, medium and small consulting firms in IE Fair from Arthur D. Little, BCG to valoris etc..
Around 20%+ of students go into consulting and I believe that's a decent ratio
But getting a job in your area of interest depends on other factors as well. i.e your local language skills ( Spanish) , prior work ex, ur grades in MBA etc etc..
As far as IE is concerned, if you are looking for ajob in spain, you don't have to worry about anything provided you are good at spanish. After spain, some of the students go to London as well.
to get a better picture, I suggest u get in touch with Adcom.
IE has rolling admissions. But its always suggested to apply as early as possible.
