实在没分了..见谅 我要去参加面试
Dear judges:
My name is …,and I am 25 years old.I have graduated from a vocational school,but now I am studying hard to get the bachelor degree.
I used to be a webpage designer in a large network company,which requires a sense of self-confidence and a working attitude of perseverance.And after training myself so hard,I think I have gained these qualities,and they will become one of my advantages over other excellent competitors.
And I,now,grow up with an extra sense of responsibility and maturity after several years of experience.I believe that I can express my personality and show my ability all the more while working in your company,and deal with the challenges in my work.
As for my daily life,I do have a wide range of hobbies,such as singing,basketball and swimming.Besides,I am keen on organizing extra activities for my friends,and enjoy myself a lot.
I am fully convinced that in the future,I will continue to study to improve myself.While grasping more professional knowledge,I will enhance my moral standard as well,being a law-observer and an upright person.In a word,I will spare no effort to be a qualified employee.
Thank you for listening.
