There are companies in India where people are coders longer than five years (I was at one).

My gut feeling (inferring from conversations) is that the vast majority of companies do not perform work of sufficient complexity to require more than three years of technical learning. The only way employees there can then add value to the organization is by becoming a manager.

Just one question, is this "after 5 year i should be a manager" sustainable? How many managerial positions are available?

Usually these are only a small percentage of the total... and to have something to actually "manage" the manager/employee ratio must remain somewhat constant (or that "add value" become meaningless).

Software services companies in India grow very fast since many are they're tapping into the offshore outsourcing (or offshoring) trends.

It appears that they've been able to sustain it for the past 20 years or so. I agree it's not sustainable indefinitely.
