I worked for them for a short time, but sensed something was very wrong within the first 3 months of my time there, so I quit abruptly, even though I had no other job lined up. I am certain it was the right decision, especially after seeing the horrible reviews here month after month, countered, of course, by the glowingly artificial 'great' reviews (does anyone really express themselves naturally how they are written?) that are obviously fakes.
It's your choice, but you can do better just looking elsewhere without any inopportune headaches or leftover heartburn. After walking away being told I just didn't meet their standards (joke), I now have a job that pays twice what my salary was there. I also understand how precarious the future of the company is, given the way they actually make their money after researching them (should have done it the first time) long and hard.
