The answers depends on your skill/subject. I have given these kind of interviews many times. The general about the interview that first of all you must be confident towards your interview. Revise your syllabus properly mainly basics about the subjects because mostly answers put from basics which we are not prepared properly . Also in case you are not answering the question they give chance for you. If you have any favorite subject. So prepare your favorite subject also. As you are more familiar with the interview you get more idea about this. Don't lose patience if you are not selected but overcome your mistakes you suffered from. Some get selected once for some it takes time

In your written exam you will be having a group of questions regarding your discipline. Some times some G.K questions will also be added. Normally the exam deeply reflects on the basics of the subject. You need to be very strong on each and every subject basics of your discipline
