As you've not asked about a specific program, I'd like to tell you about my cousin's experience at NMIMS Mumbai where he studied the NMIMS SBM core program. 

Pros

• NMIMS ranks in the top 20 institutes in India as one of the top private institutes.
• There is no reservation or quota seats.

• Faculty to student ratio is good as well, despite the big batch size.

Cons

• It's an expensive institute 
• The hostels are insufficient and many SBM MBA students have to reside in apartments near the college.
• The batch size is adding up each year hence placements might become a war zone in the near future.

So, if you're considering pursuing an MBA, NMIMS, Mumbai, is a fantastic choice

Yes, there are equal chances of both freshers and experienced employees to get a seat in NMIMS. There are several aspects that a candidate needs to consider to get a chance in institutes like NMIMS, and some of them are listed below in points.

• Being a fresher or having some experience in the industry does not matter much. The main things that matter are the entrance scores, along with the candidate’s performance in group/case discussion and personal interviews. 
• You should focus on your preparation for the entrance exams.
• During the interviews, it is good to have an interesting profile that you will discuss and showcase. So, internship and extra-curricular participation is a good thing for building a top-class resume.
• You should have a clear vision about your reason for pursuing an MBA, along with a detailed description of matters of interest like Finance, Marketing, HR, Operations, etc. The PI round mostly revolves around these aspects only.
• There are some institutes where academics play a very crucial role. But, that is not the case with NMIMS, giving very low weightage to academic results. 
• In general, NMIMS gives 70% weightage to NMAT score, 15% to CD and PI scores, 5% to work experience, 5% in gender diversity, and 5% to academics.
• In the 2018-2020 batch, there were 27% freshers, which makes it quite evident the chances of freshers in the institute.

Therefore, freshers can definitely get a seat in NMIMS, provided they have the correct profile and perform well in the entrance, CD, and PI rounds.

Do not believe in the ranking of the college. It will cost you if you are not a resident of Mumbai as the college does not have a hostel and spending this much amount for an MBA is really stupidity.

You will get an average package of around 12.5-13 LPA for core and 9-10 LPA for HR. Also, the college charges separate amounts for GDPI round and after the release of results, the college demands 9 lakh be deposited immediately within a week.

Also, it is believed that sitting in centralized AC and roaming in posh areas would not help in your overall development but exposure to different fields prepares you for the professional front.

Lastly, we can say that spending too much without availing facilities is not worth it. So abstain from getting admission here. Instead, take admission in other top management colleges where you get exposure to various other fields as well.
