When I've seen bad jobs done by Indian companies, it has generally been as a result of poor project management from the client. Given the right milestones, targets and contractual obligations, and no goalpost-shifting, the results get better.

That said, I heard tell of a piece of code where "if n < 20" was implemented as a series of 20 "if n = 0", "if n = 1" conditionals, which beggars belief.
