For fun, let us try to help them out with some suggestions:)
I dread that they will end up with the mahaan manav's mechanic profession !! I just cant imagine Arjun under the hood, so to speak !!! he probably doesnt even have the exp for it.
It still kind of boggles my mind that he cannot use his certificates bec it has his last name. Experience, yes i understand that. There can probably be hundreds of people in india with the kirloskar last name !! And, the name kirloskar is not like the tatas or birlas that everyone would know about it !! Anyway, that is my view point. Who said dramas are logical, anyway...
So, i think the best job would be to be a cab driver in mumbai. This is one talent he has as he can drive being brougt up in cars !! He can even go to the same agency as teju. And cab drivers in mumbai can easily earn the 10000Rs In a week. There u go, arjun!!! Easy solution...
