My friend recently flunked her interview as she did not prepare for the questions related to her undergraduate degree. They asked her to start with a basic introduction after which they asked her about the subjects of her undergraduate program. Because she had not prepared well for this part, her hesitation took the better of her. They probed her with questions like
Did you study Financial Subjects or about to study?
What worsened her situation was the questions asked by the second panel. She asked her some mathematical questions which became the reason for her doom.
The conclusion from the interview is that as a fresher you should definitely go through your graduation subjects as most of the questions will be asked from that only. Remember they will question your ability to answer the questions confidently most importantly.
