Note: All this observation are only based on my caste.

1) Expiry Date: so as a men if you enter 28 you started getting expired and as soon as you cross 30 they literally label you as a expire product(yes they use word expire product).

2) Rate card(this is interesting) :

Their are some checks that you all need to pass:

a) Is your job is government/business/private

government > private(50k ) > business

If you pass this round

b) Your house and ancestral property

First you can't be in rented house. You need a minimum amount of land(it can varies according to girls family)

Your house should be well build

c) Looks matters d) If you are good looking then did you look good with that girl or not.

So what type of girl you can marry.

If you mark all the checks you can marry anyone you want.

If not then it's a bit problem.

I am M24 and I observe all things while I was going through arrange marriage process and my cousin sisters and other people are also going through arrange marriage process.
