...lots of new immigrant need a chance to proven himself or herself in working environment. You know the current job market environment is not too good for new comer. So most new immigrant must write some false information in his or her resume for applying any kind of job. Otherwise they never can get a job. And because this reason, most recuriter doesn't trust our experience which was written into our resume who come from China.
So the guy killed by u question will write that he is Seinor in Java Programming next time inorder to get a job.
Why?Just like you say "he doesn't know the true reason"
Another Word in chinese "得饶人处，且饶人", 别总往命门上捅，尤其是对中国人。
