Hi aspirant,
Choosing  the finest place for study is quite a cumbersome task and one needs quite a good amount of time to think upon the same. Well, coming to your question that which institute is better among IBS and Globsyn Kolkata, I would give you some basic parameters over which you can take your final decision.
In terms of placements Globsyn is good ,every year and this year around 100 students got placed within 45 days with an average package of 5 lacs per annum. All the students got placed in good and reputed companies like Amazon, Nestle, Dabur, Asian Paints, Berger Paints, TATA Motors, Axis, ICICI etc.
Internship opportunities in IBS ARE MORE
The college provides international and domestic internship based on the academics of the student. Any good student can get the chance to do the internship in some best companies.
While the curriculum is almost the same in both the colleges and both of them are well known for its faculty. Hence, I've given the points in which students are most interested. So, here choice is yours.
Hope it helps
Good luck
