my interview introduce
It's my pleasure to have the opportunity to get an interview. My name is Gary. I was born in Zhongshan. I graduated from Shenzhen University with a degree in IT network.
I started off my career as an IT engineer in media. I was in charge of the IT helpdesk and network. I had to problem solve and make some network workable. It was a wonderful experience, because I saw how the IT department worked in the big enterprise.
Secondly, I worked for BMW 4s shop as an IT manager. I was responsible for the 4s shop network building, the helpdesk, and installing software. Although <s>just one person.</s> I was the only person in charge, I successfully <s>make the shop open in time </s>opened the shop on time and solved the IT program. It made me learn for myself.<s>And I have to solve some problem quickly.</s>
I was in that position for 3 years. Then I had the chance to be the IT engineer for Danone.
Although I was an outsourced engineer,<s> I have to in charge of danone zhongshan plant for IT,just me</s> I was solely in charge of IT at the Danone Zhongshan plant. <s> </s><s>I have to in charge of solve computer problem,and network problem, ,telephone,email,and some program</s>. My duties included solving computer and network problems, managing the telephone and email, and programs. (And monitor.?) <em>I always server foreign workmate sovle computer problem,and I call communicate well. (</em>I'm not sure what you are trying to say here.)
<s>I think</s> I am fast learner and and an outgoing guy. Globalcare is a world leader in the design and manufacturing of medical devices. I really hope to have this chance to join your company.
===============================
I've made some corrections and a few suggestions here for you but it can be edited further.
Remember to capitalize proper nouns, such as the names of universities and cities. Also remember to pay attention to tense. You were often switching from present to past tense and I wasn't sure if you were talking about a past job or a current one.
Great job and good luck! I hope you get an interview!
