No explanation, just email w/instructions. But here's what I find interesting...at the end of the survey you can sign up to participate in other surveys...just enter your email. Hmmmm, well wouldn't that mean they can trace the survey back to you? I didn't answer honestly because I don't think this company has an honest bone it it's body. I think people who express disastifaction on the survey will soon find themselves on the brink of not having a job. Just my two cents.
