In July 20xx, I began working for a small private company as a technical support engineer in Qingdao city. Because there was no more chance for me to give full play to my talent, so I decided to change my job. And in August 20xx, I left for Beijing and worked for a foreign enterprise as an automation software test engineer. Because I want to change my working environment, I'd like to find a job which is more challenging. Moreover，Motorola is a global company, so I feel I can gain a lot from working in this kind of company. That is the reason why I come here to compete for this position. I think I'm a good team player and a person of great honesty to others. Also，I am able to work under great pressure. I am confident that I am qualified for the post of engineer in your company.
That’s all. Thank you for giving me the chance.
