Farooq - you are taking on Dipankar my Bengali brother in arms in a abusive manner, it seems you are from Marathwada region of Maharashtra where the rudest people in India come from. I do not wish to stoop to your level but it is evident that far from being an MBA, you would not be able to even spell MBA properly.
What Dipankar is saying is absolutely correct. People like MS Banga have actually sold soap in the remote corners of India to know the market and the mindset of consumers. It is this grinding and rigour which has made HLL (now HUL) the most fantastic training ground for CEOs. You have to also see people like Mr Murali Sivaraman, MD Philips who started his career as an IT consultant for ICI, or see Ms Lalita Gupte - a law officer for ICICI. Someone like Subroto Bagchi came from a humble family in Orissa and rose to the pinnacle of success in Wipro.
There is no substitute for hard work and rigour and you must know the process to learn and earn. You must get your hands dirty and work in a focussed manner and in this respect, your boss plays a critical role in evolving the job for you.
Bill Gates, Steve Jobs are exceptions rather than the rule. I would rather go by people who worked in one company all their lives and grew with the company and enriched and contributed to the welfare of the organisation.
And lastly, never make the mistake of taking on a Bengali - we are the springing tigers of the land - read Hugh Troys biography of Netaji.
