Perhaps discuss why you chose your major. If you have some personal stories to to tie into the reason you chose your major it would be better than "I majored in accounting because I wanted a good job". In an interview they want to see who you ARE more so than what you know. Anecdotal stories will give the interviewer more insight into your personality.

"I will am having an interview in a few days,and they told me that i am supposed to talk about my major.I have no idea what to say; if you were in my shoes,what would you say?" umm 1st of all what is your major?? and 2nd of all ..is this interview strickly informational? or do they want your opinions and ideas about it? ok .. well if they want your ideas and opinions along with information the i think you should talk about why you like your major and what made you want to pick it. then i think you should talk about what you major is about and how it helps the people around you. once you have covered all of that explain what your major is about and the complexity of it along with the good and bad aspects of your major. and another thing you might want to consider incorperating in to your speech is the history of your major.. and the profesors or people who have made your major better or have helped you to decide on this major. that is if your speech would be to last a fair amount of time. i hope this helps! ... if you give me more details i can probably help more :) ok .. well good luck! and hope you have a great day!:) ~nicamamii~
