Agree on this one -- 有强的专业能力+不错的性格就可以了. This is also true in the United States, especially 不错的性格, which is very important in your career life. I know some people from top schools miss this point and could not do well in company...
Actually, even graduation from top schools does NOT guarantee you a job offer. If you are strong, you will stand up sooner or later (I can say within 2 years). If you are weak, a degree from top school just let others doubt how did you slide into the school... :-)
The last thing, no school will be responsible for your employment. This is not China. Even now, Chinese schools do not be totally responsible for students employment, right?
