Doubt on Work Experience?

Hello Friends,

I have a doubt related to work experience, if one is doing articleship from small firms is not counted as work experience if he goes for mba..rght?

and if a person does a job in big audit firms such as pwc, delloite,etc.. then will it be counted as work experience if he goes for MBA(finance) after inter.

Is it worth 2 do finance jobs in other companies or its better to do in audit firms to gain better experience which would help in MBA(finance)

Please clear mydoubt as soon as possible..thx
