IIIT A is not an IIT nor a parody of IIT it is a government college and is better than many NIT's even many new IIT's choose according to their preferences and go for it.

Both PGDIE and PGDIM are very good courses for a mechanical engineer, but the syllabus for both these courses is different. 

PGDIE

1. It is a flagship course of NITIE which is more focused on industrial engineering. To get admission to this course, you have to clear the GATE exam.
2. As a fresher, you can make up with most of the students in your branch but you might not be able to contribute as much as the students who have significant experience, especially in class discussions and group activities. 
3. But there won't be many problems during placements as there are many companies who are looking for fresh candidates to join their team, especially in the FMCG sector. 

PGDIM

1. It is a management course that is equivalent to an MBA course, and to get admission in this course, you have to clear the CAT exam.
2. As a fresher, if you take admission in this course, you would probably be in the minority as most of the students would have some kind of work experience. 
3. There will be certain projects which would need some kind of experience and here your other batch mates can be a step ahead of you. 
4. You will have to do a lot of reading and communicating with all your batch mates, professors to learn how a business works. 

Both the courses are very different from each other and now it depends on you in which field you are interested in. If you want to pursue a management course then go for PGDIM or if you want to be in the field of engineering, then you can choose PGDIE.
