Distance learning can be beneficial or it can't. It all depends on the types of businesses you applied to and the standards they used for hiring.
Amity University is a well-known university among others. They do give its freshmen and graduates improved placement prospects.
Finding a few current students who have completed a distance learning programme is all you need to do to acquire their feedback.
I am unable to offer any opinion on such a business or person. You must conduct research.
