Bookish theory knowledge is important. But to an extent. Get to know about what is happening currently in your branch around the world. For Chemical Engineering, petroleum sector is major recruiter of Freshers. So be acquainted with current happenings in petroleum world, renewable energy and research being carried by petroleum giants in India to shift towards Renewable energy. It's a good sign if they're convinced that you're aware. If your CGPA is low, an explanation for it is always beneficial. So keep one ready, a genuine one.
