Dexter Systems (Virginia) Java Developer interview questions

I applied it on university job finder, and get emailed asking for very simple information like what position am I looking for, which is exactly the first line of my cover letter and resume. I replied them once, and they asked the same questions again, and I replied the second time. Then one day, a man with a very thick Indian accent called me and ask me questions like what position are you applying for? How good are you at Java? Then he talked something I totally cannot understand for 5 mins, I only get a few words seems that they asked me to pay them for some training program. (I am not sure because it is very thick Indian accent). Later they send me an email ask me a copy of my passport and driver license and EAD( which the driver license is indicated as not necessary in the email). They also send me another email to let me confirm the position again...
