Hi Rashmi,
Interior design in India is currently trending in India with a lot of students opting for it. The future for this course is really bright. Speaking of jobs, you can get into government sector jobs like
1. Municipal Cooperation
2. Town and country planning
3. PWD
Etc also now with smart city initiative by the government it's easier to find a job in this sector.

You can work for organisation like the interior design firms, furniture design, home designs, Architecture firms etc which offer a high pay.

If still not satisfied you can alway work alone like an entrepreneur and maybe provide jobs for people.
Good luck
