IIM

It would be hard to predict. Given current state selection criterion, it would be very hard for you to get admission call from IIMA, B, I even if you score 80%+. This is if you are from general category.

Hi Kishan,
It's not the case, however, being from a good college would mean that you have already been in the best environments and have learned quite a lot from your time there.

Extracurricular are anything that you love to do. From your bio I could see you love to dance and play badminton. In the interview you can speak about that. Apart from that you can start writing in Quora, read novels, learn new languages, paint, cook, learn a new game, etc. Basically if you are passionate about something, do it. In the interview the interviewers are looking for passionate dedicated people. Show your enthusiasm and ace it.

Hi,
Yes, you are eligible for getting admission in IIMs.

Dear Arun,
I am afraid to say that with this profile, it is very hard to get admission in Top IIMs. Since you do have below 90% in class 10th and 12th. This might decrease your percentile formula for CAT. Second thing is; since you do have 2 year of gap after 12th, you need to justify a very concrete, true and logical reason for this gap because admission committee may ask you about this gap and may create an impact on your selection.
Based on your profile, I hope you belong General Category, you need to score 98%+ in your CAT exam. Scoring this, the chance of getting IIM-Bangalore / Calcutta / Indore will rise up.

Majority of the IIMs require minimum 98 percentile.

FIIB is one of the best tier-2 college other than IIMs for PGDM.

Just be very sure to get good percentile in CAT above 98 percentile should be fine. But having said this, this can not ensure a call from any college. As there are n number of factors into play. But you should focus on the factor that can be improved and work for written (CAT) with full efforts.
Thanks.

Hi Swapnajeet,
Some disadvantages (if you'd classify them as)
1) Annual fest isn't as popular or vast.
2) Comparatively less popular in non-corporate social circles.
3) No full trimester exchange programme.
4) Campus in DU (that can be distracting sometimes due too all the other activities happening).
5) Not all students stay together or in immediate lanes.

There is no preference rather criteria. The experience should be either in a listed company in NSE or BSE or a well reputed organization such as MNC. Like, Sony is not a listed company in India, but a well-known name, hence acceptable.
