I have a few friends from NITIE so I can give you some information regarding admission to the institute. It accepts GATE scores for PGDIE, PGDMM, and PDPM courses. They shortlist students for GD-PI based on their GATE scores. The required cutoff for GATE varies every year, due to many variables. Here are the cutoff trends for 2021.

The GD-PI round will have 60% weightage for your final selection and the remaining 40% will include your GATE score, academic records, and your work experience if you have any. 

Hence, the GATE cutoff for every branch in NITIE is the same but you will also have to perform very well in your GD/PI round to get admission.
