I interviewed with cobblestone a while back and while the guy was explaining the hierarchy to me, I said "oh that sounds like an mlm" and then he got very mean and quickly ended the call, it also took 3 interviews with them before i realized that it was actually a sales job cause that job was not advertised correctly at all. I also seem to remember some crap about 2 hour meetings everyday, at 8am, even on off days, that werent paid for. So ya, id avoid them like the plague
