Hello there. Hope you are doing good. I would like to tell you that the scope of M.Des in interior design is really good provided you are dedicated and passionate towards your field of study. The placement opportunities can also be decent but it is subjective to which college you are graduating from and what is the placement scenario of the particular college. In general, if you have got the required skills, you can also look for placements outside the college or institute.

I hope you found this answer helpful. Good luck for your future.
