IIIT Hyderabad MSIT course is perfect for someone who has a flawed academic profile like a gap year or something. People like these have very limited opportunities so this course might uplift their chances of getting placed decently. However, since you specifically asked, this course is not a good option if you have an IT background. This is because the curriculum is repetitive and covered in a shorter duration. Also, if you are employed, it’s better to invest your efforts in improving your work experience than wasting time on this course.
The placements are decent and in fact, during the first phase, you might get into top IT giants like Amazon, Salesforce, American Express, etc. But if you fail to get placed in these then the only option left is to get into service sector-based companies.
So, this course is best suited for those who are looking for a means to upgrade their academic profile.
