Fresh from her college university, my cousin who was applying for a position in a business company made sure she was all ready for the scheduled interview. Because it was her first time to hunt for a job and be interviewed, she called me to seek advice.
So I told her to first research about the company's profile so that she has an idea of what the company she is applying to and second, she just need to practice answering impromptu questions while having eye contacts with the one she is talking to. To make the story short, she made it. She said that during her final interview, the big boss was so impressed with her smartness that he gave her a signing bonus! Impressive!
