I had a telephone interview with the folks at bluniverse in HeFei about one year ago and that experience alone was enough to tell me to avoid them. After careful questioning they finally admitted that the position was not actually in HeFei but they were sending teachers to various, remote parts of Anhui -- no thanks!

After that experience I have kept a lookout for posts regarding bluniverse, and no surprise, every post I find (on this and other forums) is negative.

If you're invited to join bluniverse, keep your job search going in another direction.
