HIT - Haldia Institute of Technology

According to the present records of placements, Haldia Institute of Technology is far better than Galgotia.

I can't tell you about the current cut-off but you can apply for the joint counselling. And CS is not important. Once you are admitted at any branch, after that, you can score more than 8.5 CGPA in 1st year. So, you can change your branch to CSE. Your 1st year syllabus for every branch is same.

If you go for the labs, Haldia Institute of Technology has better labs as compared to Heritage Institute. The placement percentage of ECE is 100 percent in Haldia Institute of Technology.

Well, being selected for the highest package totally depends on you. There is no fixed criteria for the highest package for any of the departments in any of the engineering colleges in India. So it totally depends upon your skills.
And for your answer to the question you asked, one student from our campus got placed in Bosh and his package is around 8-10 LPA. There are many more students who are on a good salary package.

In IEM, civil branch is not there.
In Heritage, you will not get civil branch.
You will get Haldia college either in the 2nd round or the 3rd round.

There are several companies which visit our campus and for CSE the best and mass recruiter for now is Infosys. The maximum salary offered by infosys is 6.5 LPA. Other companies which also visit our campus offer a maximum salary package around 14 LPA which is the highest record yet.
