如果是HR主动找到你的，一般不会要你自我介绍（你主动去找别人还好意思要别人做自我介绍？），只会要你介绍一下自己的工作内容。你就只要把我下面说的工作内容分一二三几点说出来就好了。
如果是你主动去投的简历，那你就要从头到尾系统地把这个自我介绍做完。
Good morning XXX. My name is Steven. According to the JD(job description用专业术语，HR都懂的), it seems you are looking for XXX. And I am also a XXX in XXX company.
介绍一下自己的工作内容VS.招聘要求。
As far as I can understand from the JD, this job requires XXXX（提炼几个核心的要点，分一二三列出来). And my current responsibility is taking charge of XXX , which includes 3 major parts（不管怎么样，都要分成几方面说，哪怕真的只有一部分，你也要分成几部分说，这样才能显示出你的条理）
如：
The first part
is xxxx
The second part is
xxx
The third part is
然后总结
This is all what I'm currently doing and I guess it should be close to what you require. It would be great if you can share more specific information about this job such as... (反问问题，针对你想知道的工作内容提问，把球踢给面试官，不要让他有机会问你问题）
希望能帮助到你，望采纳！
