I got a hang up call from this number last night (Nov 14, 2014) at 6:30 - I don't know anyone at that number. I just read that hang up calls after 1 ring could be a computer generated call that charges you a per minute fee to call them. They send out mass calls and know that even though 99% won't get a call back - there will be someone hoping it's the company they interviewed at, or the girl/guy they are wanting to date...
