1. Phone Interview 2. Technical Interview 3. On-site Interview I had my Phone Interview with Sitka Technology group 2 days ago. HR called me and first question was if I have U.S. Citizenship and if I don't, do I have valid work visa. As an International Student, I have my OPT for 3 years. But after this point, HR told me that they do not sponsor and suggested to stop Interview right there.
