My name is **. I am 23. I just graduated from ****** University and majored in secretary. I am an out-going girl/boy. I had worked in the Post Office and Insurance company. In that period, I worked hard and got on well with my colleagues.

I like listening music, doing exercise and watching movies in my spare time. If I have the honor to work for your company, I will try my best to obtain the excellent result and creat more benefit for your company.

建议楼主把'性格开朗'放在第一句话后面.我的英文翻译就是这样的，我觉得这样比较好.
