MIET has a good campus and it remains one of the USPs of the institute over other colleges in the region. However, you should worry less about campus quality and more about the academic quality offered at MIET. Placements are OK, considering it is a UPTU college. Most companies which visit KIET, AKGEC and other UPTU colleges also visit MIET, so you shouldn't worry about this aspect.
Best of Luck for the upcoming admissions season!!
