A bunch of guys from my employer have looked into regionals and CFI positions in India. Time on type, especially PIC is needed for the scheduled stuff. Their are limited coperate oppertunities but they will also want turbine PIC.
The guy I talked to there (a "headhunter" for an agency) told me there is a background check that takes at least 2 months. After that you have to take a checkride but my understanding is that there are no written tests because your Indian licence will be based on your UK licence.
If you're Indian all you need is to at least have seen an airplane once (or have a father who has).
Best of luck,
Derek
