I applied online. The process took 1 week. I interviewed at General Motors (GM) (Charlotte, NC) in Feb 2015
Interview
I got two phone interviews in the same day after applying online for a week. The first interview ask me if I have working authorization in US and background checking. After telling them I have J1 VISA, they said they can not afford for this situation, and cancel the interview.
The second one is cancelled after the first one, since I am in J1 Visa.
