There are basically 2 steps for getting admission at NITIE. 

First, you need to clear the GATE cut-off in order to get a call for the GD-PI round. The GATE cutoff depends on the GATE score and not the marks. The required GATE cutoff varies each year depending on the application pool. However, the cutoff stays generally around 650-700. Here is the GATE cutoff for 2021.

Second, after you've received a call you will have to ace GD and PI.

So, if you want to get into any of the postgraduate PGDIE/PGDMM/PGDPM programs, you must build a very strong profile.

One of my friends cracked it last year. So I might be able to give you some information about it.

• NITIE has successfully attracted the best talents and has always been in a student's top choices.
• During the admissions process, NITIE questions candidates on a variety of parameters.
• In my friend's case, he was asked a slew of questions about his engineering knowledge, summer internships, extracurricular activities, and hobbies, as well as the standard ones about why he wanted to attend NITIE.
• Like in any other B-School, there is a stipend for every achievement of a candidate. The winner achieves a set score level.
• I would say that excelling in one field is unlikely to get you through; knowledge of all fields is required to pass the test.
• In order to pass the exams, you should be good in analytical and problem-solving skills, which typically come from good mathematics skills. 
• Communication skills are also an added advantage.

For your current studies, if you are using high-quality reading materials from top publishers, that should be sufficient. Aim high and you will succeed. Just keep working hard.

According to my knowledge, the admission procedure is simple. There are some points you can keep in mind during the selection procedure.

Here are some of the basic points for the selection process of a candidate for PGDIM course at NITIE:

• Candidates must have a BE/B.Tech degree with 60% from any branch from a recognized university.
• They must have a valid CAT score.
• If you are appearing for your final year, you are eligible to apply.
• You will be shortlisted by your CAT score.
• The shortlisted candidates have to sit for GD and PI in the NITIE Mumbai campus. 

Remember one thing, present your best self, and if you are chosen, think wisely and then make any decision. Not only your GD and PI scores but also your class 10, 12 and graduation scores will also play an important role.

I can give you an idea about the cost of doing an MBA from NITIE as one of my friends is a student there. At present, the tuition fee for MBA is 11 lakhs for a period of 2 years.

Other than that, if you consider assuming Rs. 3500 as the average mess fees for a total of one month, then it sums up to Rs. 35,000 for a time period of 10 months (considering 2 months of vacation period).

The mess fee sums up to Rs. 80,000. The overall amount you might personally require can be 1 Lakh in a total of 2 years. Thus, it can possibly be around or over 13 Lakhs, if you go on to plan for a rather controlled cost vacation in NITIE.

According to some of my friends studying at NITIE Mumbai, the 12th standard marks are very important and it matters a lot during admission for graduation and placements. Having good marks in the 10th and 12th standard helps a lot but it is not the end of the world. 

• Companies that visit the campus for placements have their own individual preferences. 
• Some companies give preference to 12th standard marks, but this is not the case with every other company. 
• Many companies give preference to college scores and recruit candidates based on their performance in personal interviews and group discussion rounds. 
• Some companies also look from which tier college you belong as they only want to interview candidates who have passed out from a tier 1 college. 

There are several other factors that are important for placements. Like extracurriculars, additional skills, etc. Thus your 12th standard mark isn't the last thing. A lot of other factors matter for your campus placement in NITIE. 

You didn’t mention your branch, which makes it difficult to draw a conclusive comparison. NITIE is known for its Industrial Engineering course. 

If you are talking about Industrial Engineering is definitely the better option as compared to IITs. It offers great placement opportunities for Industrial Engineering students. The average CTC offered at the institute is around 20 LPA. In 2021, the highest CTC offered was 44 LPA. Such salary packages are unheard of for M.Tech courses at IITs. 

If you are talking about branches other than Industrial Engineering then you should first figure out which branch interests you more, before choosing an institute.
