Hello khabar,
As i know and heard of around, it depends on company. Different companies have different ways to place you full time from contract. I know they will do BG for sure but not interview process. Some might check your degree and also check 5 years payroll. Some companies don't.
I think best will be to check at your own company policy or ask some other Nepali or Indian how is the process and all. It might help you.
