I have done an internship in HR (PepsiCo India pvt.ltd.) and my roles and responsibility were I worked with salary payroll and management with employees hiring. It's not salary during internship stipend paid by company INR 5000 per month.
Yes, mimt college provides many placements as you saw on the internet.
They do not provide any internship, if you want to do, you have to search it yourself. Many companies like jubilant, cord life visit the campus for recruitment but the package given is a bit low.
