When I said I was on OPT and would need visa sponsorship in 28 months. The interviewer hung up the phone and exited the gotomeeting platform. I spent an entire day to refresh some skills (not really a waste of time but still!). The interviewer did not respect that. Very unprofessional but indeed the interviewer seemed more stressed than me, a beginner maybe. If they couldn't get from my profile that I am a foreigner, they are retarded. First time a company does that to me. Anyways, I could have brought a lot in their life, and also a lot of money because I am an excellent worker, so their loss. I thought I would be more mad than that, but in fact I feel very lucky I saw their true face before it was too late(if i had been a us citizen)...
