How do I prepare for case discussion and personal interview process to get admission in the MBA program for NMIMS mumbai?

One of my friends has recently been in the interview session at NMIMS Mumbai and can explain it better. Here is what he has to say,

1. The Group Discussion (GD) at NMIMS Mumbai is usually quite similar to the Case Discussion pattern.
2. The only difference between them is that, in Case of Discussions, you will generally be given a scenario or situation where you will need to justify, analyze and evaluate possible solutions and later come up with the most suitable answer, while in Group Discussions, you are usually allotted a topic to discuss.
3. The best possible way to prepare your problem-solving skills is to practice in groups of about 10 to 15 people.

For the Personal Interview Session, you should usually follow these:

1. You must read as much as you can about the course you are about to go for.
2. The current social and economical issues are mostly following up in and across India.
3. The various economic sectors and their effects.
4. The latest schemes and policies adopted by the government and their general effects.
5. If you possibly have planned your specialization, you should undeniably know and read more about it.
6. Prepare certain general questions, such as the introduction, why you are going for an MBA, and why have you considered pursuing a particular specialization among many others.
7. Know about your strengths and weaknesses, your achievements and failures, and how exactly will you project your achievements in NMIMS, Mumbai.

The major hack is to receive important feedback and practice daily to know where you are relatively going wrong. Besides, read new topics every day.
