Beta Soft Systems gave me a call this morning wanting to hire me on. I could barely understand the person talking to me. She had mentioned some sort of "black box" training program that lasted 5 weeks. She said that this program would enhance my resume and make me more marketable. What she didn't mention, until the end, was the $1000 security deposit that would be due on your 3rd training session! Apparently, it's refundable after getting your 2nd paycheck through them (which, they're a staffing agency, so I don't know how that works...), but who has that kind of cheddar to pay up-front? I checked the website and they look legit, but I can't be sure; it seems sketchy.
