Hi Tanushree,
In the second year of HM, you can go for Industrial Training, which will be in all 4 departments and in 3rd year you go for OJT- On Job Training which will be as per your choice of department. Jobs are as per your selected department. HM has huge scope for international internships and placements. UEI Global has more than 10% students every year going for International internship.

It is difficult now after UK has imposed so many strict rules for Indian students. So, it is a risk and won't be recognized by many and UGC.

Yes, you can. JEE is an entrance exam getting admission for all over India Engineering College, but GUJECT is engineering entrance exam for Gujarat Engineering College which gives quota prefers more for Gujarat Residents. Both Organization organise on their own and interdependent to each other.
