IBM Associate System Engineer interview questions

We got only 1 technical interview in which they asked me mostly hr questions and project-related questions. Also, some questions related to theory of one of the subjects which I like the most. And some questions about my extra-curricular activities.

The interviewer asked me some basic techincal questions and my branch core subject related questions. Techincal questions are from programming language from which I am comfortable for answering. And also one hr related question - being ECE, why to enter into this IT field
