The 1000 hours TT, or 500 Multi, or TR + 100 hours on type, do still apply, these are India's DGCA requirements to convert a foreign licence, so unless there is a regulatory change (which it is not likely in the near future), these are the minimum requirements to fly commercially in India.
Regarding other programs, SimCorp doesn't publicise any other, so apparently they don't have any other internship program.
