Good morning Sir, (What will you say if it is a woman?)
I am glad to be here for this interview. First, let me thank you for finding time in the midst of pressing affairs.
I am 25 years old and I am local. (I live locally sounds better) I am seeking an opportunity to work with XXX as Sales. (..IN sales or As a Sales representative/whatever).My professional experience and my awareness of your unparalleled reputation have led me to want to work for your company.
I have a bachelor degree with a major in Mechanical and Electrical field.(pause) Graduated from the XXX university in 2002. Over the past three years, I have worked with XXX Co.,Ltd as Sales (again, in sales or as a sales man/person/rep?) who responsible (with responsibility mainly) for the market of Hunan. During this period, I have learnt much. I learned the values of teamwork and commitment, how to win, how to work hard, how to concentrate and focus on goals, and how to balance my time and priorities. Additional experience in other fields such as graduation practice in factory and commercial negotiation also reinforces my value to your company.
I enjoy thinking, enjoy learning, enjoy working, (and I am )able to bear work pressure.
In my free time, I often participate (in) activities such as table tennis (and) badminton.
I am expecting to become your colleague on some day. (More tactful to say ’I would love to become you colleague/join the company)
Because being offhand in advance, let’s leave it at that. (This sentence makes no sense. ’Being offhand’ means to be rude, inconsiderate, ill-mannered so I don’t think that is whay you mean! In advance of what? ’Let’s leave it at that’ is a command, it sounds rather abrupt and ill-mannered to me, again I don’t think this is what you meant. How about ’I would love to join your company and you would not regret giving me this opportunity.’ and just finish with a smile!)
