My friends said I could file a lawsuit against them yet I don't have time for legal engagement. If a U.S. citizen or permanent resident is qualified for the job then he or she should be hired, whether they want to apply for green card for their existing employee or not. That's what Equal Opportunity Employer means. I guess Dell does not comply with the federal labor regulation. Then one of my former coworker who is a U.S. citizen told me that he applied for a Process Engineer position at Dell and the manager told him that, within a week they received 2,000 applications and most of them are from India. He then told me because most engineering jobs at Dell are occupied by Indian people who refer their Indian friends for engineering jobs at Dell every day. He also said, if you are not Indian, it is most likely you will not get an engineering job interview, not to mention a job offer. Apparently he is right because I am not Indian and my job interview with Dell was not real. I was used for them to test the market and benefit their green card process. There is no diversity at Dell engineering department. 99% of their engineers are Indian even though they website advocates diversity in their corporate culture. It was just a joke. Also if you get rejected by Dell for one position then you will get rejected for any other position you apply afterwards, even though their rejection email says they encourage you to check out Dell career website frequently as new positions come up blah blah.... Trust me, I tried that.
