hi!!
1. Honestly speaking I am not too confident for that matter on any B-School when it comes to working in India with compensation at par with what you can get abroad. However, we need to do some research on that. I believe that after a couple of years work-ex abroad, it will be the School name PLUS the job profile we carry at that time which will fetch us some good career profile back home. Regarding brand, I believe RSM is pretty well established in India
2. NUS is an Asian school and I think that your career opportunites in Asia would be slightly higher if you graduate from NUS than from RSM.
3. You can check on the Blackboard and on web-site regarding the employment report.
4. RSM is poor in offering schols. All alumni must have taken huge loans, and most of them are recommending RSM, so I think that is quite encouraging


.
Hope this helps, sorry I myself am not adept in answering these queries fully.
