我的第一次面试，被拒了。

是Fortune500之一，在国内的机构。第一轮校园面试我还感觉良好呢，那个interviewer似乎也对我的表现很满意，还说很impressive. 后来是国内的HR和我联系，先问我薪金要求，我还满以为他们想要我呢，自认为期间没说什么错话，对他们给的薪水也没有任何异议（我认为薪水比较低，但是我也没做任何评价，也许是我最后一封信回得不够积极？）结果过了些天就来了这封信，
It is with considerable regret that I must tell you we are unable to find a suitable match with our available openings at the present time. As a result, we will not be able to take further steps with you in the interviewing process. Each year we receive a large number of applications for a relatively limited number of positions. We must make fine distinctions among applicants, most of whom have excellent qualifications. To be clear, our decision in no way reflects our judgment of your ability; nor does it indicate that we see a weakness in your background.

虽然我不是很想得到这个职位，只是想练习一下，但是被拒了还是不爽，不知道自己的问题出在哪里。也许是我还不够牛？谢谢大家帮我分析。
