Numbers?? last year how many ??? X/35 ...X=???
The reason you can't find it on the placement report is because of an important reason. All International offers are sought by the students themselves, and not assisted by the Placement Committee. At least not yet, though things are likely to change soon.
Now you need to understand that since there is not career assistance culture like a Placement committee in most B-schools of Europe, whether or not a student will get such an offer depends on how many wish to apply and how many are capable of applying. The numbers change every year and hence no particular trend can be seen. I know in my senior batch at least 5 are currently working countries outside India which include Germany, Singapore, Vietnam and a few more. I personally have met 9 of PGPIM alums during my internship / consultancy projects who are currently working in Europe / US and there are many more that I know of working in big names like AT Kearney, KPMG, BCG, Bombardier, BIC, Rocket Internet etc.
It has to be very clear that if a student wants to work internationally, it will a personal decision and then a personal quest to find it. If the candidates are good enough (this opinion generally changes once a student comes to Europe) they will find jobs here.
