They are not skilled, at least in IT or Software Engineering. They are highly skilled at lying, cheating and scamming their way through Skype interview and coding exams with others sitting the interview in place of them. There is a whole internet-based industry in based in India to have them pass these interviews.
They are highly skilled at racism and nepotism. Once in a hiring position, only those from their own religion, caste and region of India gets hired.
That hasn’t been my experience.
