IISc Bangalore has an active placement cell that conducts placements yearly. Last year the students received an average salary of INR 23 LPA and the highest salary of INR 60 LPA. Some of the past recruiters include Adobe, India Bulls, Siemens, L&T, Tech Mahindra, ICICI bank, Cognizant, Birla Soft, Cipla, etc.
As for the ME, it's a research-oriented program and has no placements. So I am assuming the scope you are concerned about is the learning scope. The ME in CSE helps largely in expanding your knowledge base and considering it comes from one of the most prestigious institutes, the course is undoubtedly exceptional. However, it's best to check the faculty profile in your related areas.
