I am an mba in finance and marketing and planning to start bussiness in a couple of years before that i would like to get trained, so if i work in accounts department will i get the overview of the bussiness.

Oh my. My wife worked for a smallish company as the A/R department and then, after she had done that for almost two years and transferred to another department, they hired some punk kid with an MBA and an empty skull as the supervisor of her new department. He tried telling her how A/R was done at that company despite the fact that she had bras older than him. Considering your grammar, I am guessing that you are the same type of guy; hiding your incompetence behind a diploma. I am a CNC Machinist yet I have an EXCELLENT overview of the company I work for. My wife had a similarly decent overview of how her company worked; production, shipping, billing, sales... THE WHOLE COMPANY! And most of her knowledge was NOT gained during her time in A/R. Unless you plan to start a business that is STRICTLY financial (brokering, tax preparation, etcetera) then I think you need to actually experience life out from under that sheet of paper your school gave you.

You have an MBA in finance and business and you can't spell or use punctuation? Where the hell did you attend college? I wanna go there! What is your primary language, dear?
