I am an Indian (though I only worked for a year in IT before leaving for actual work), and let me tell you, we Indian IT developers are a complex bunch.
3 out of 100 know the actual work, actual technology, impact of choices, etc. 80 out of 100 just get by, as in, do the bare minimum required to get by the day and the task assigned to them. The remaining are bootlickers who get promoted to management.
And there are no qualms about ethics. Want to pass a test by commenting some code? "we will do it once to check first, then we will repeat it without commenting" (and the latter will never happen). I would not be surprised if they have a "test" set of code, solely to pass the specs and an internal "actual" code that will be delivered to the customer.
Also, after 20 years or so of outsourcing, I am sure most of my fellows in MNC IT companies have set up practices and navigation rules to deftly distribute the blame such that even senior management is clueless about whom to punish in case of a failure like this.
