Frankly speaking, not all IT companies are open to all branches for placements. Most startups, management, and consulting companies give opportunities to students from all branches. High recruiters like Microsoft mostly prefer students from only the CSC, ECE, and EEE branches. Don’t lose hope; if you can maintain good grades over your semesters, then you will at least get placed in companies like NITW.
If you are highly passionate about the IT field, then prepare well and learn programming. Your hard work will pay off for sure.
