hi deepa,

It all depends on you both institutes are totally different, both offering different coursed. Both fields are in great demand so don't worry about career choice regarding placements.

If you are interested in designing field then join bdes programme.

There are only few institutes in India which offer B.Des. Study of design in Bachelor would provide more impulsive impact to the students and good understanding towards design process and solutions. There are very nice and qualified faculties in design discipline in IIITDM Jabalpur.
Program is good but the location and infrastructure are quite backward there.

Or Join nit Calicut ece if you are interested in ece branch but one thing is for sure that ece is not an easy branch specially in NIT Calicut, if you don't like electronics then think 10 times before choosing nit Calicut ece.

I hope this answer will help, all the best for the future!!
