Infosys Associate(Software Engineer) interview questions

The Interview Process was a two in one process where I had the technical interview and behavioral interview on the same day. The technical round was just going through your resume of which programming languages are you comfortable with (I chose Java, JavaScript, SQL) and asked me technical questions for each programming language(Don't be afraid to say "I don't know"). A week and a half later I got a call from my recruiter of a verbal offer.

DO NOT APPLY if you are someone with authorized to work in the USA. I had applied for associate developer job and I did get hired but at the end Infosys people told me that they can't hire because I am not the citizen of the USA. Though I have a valid employment authorization Infosys still denied me saying that I am not American citizen. If that was the case then why do Infosys have no racial/color/nation origin etc discrimination mentioned on their website whereas I have first hand experienced this discrimination from Infosys. Infosys even mentions on their job posts that people authorized to work in the USA are encouraged to apply. If they don't want to hire people like me then why do they try to show that they care about us? This was a very unfair treatment from company like Infosys. Deeply saddened not because I got the job and they took it away saying I am not the citizen of the USA, but because of the fact that they made me go through all the process, even did false claim saying equal hiring opportunities. I wish there were somebody who could take care of things like this. There are millions of people who have a valid work authorizations and talents to do different levels jobs. I honestly did not expect these kind of discriminations from a company like Infosys.
