I have worked for them for a little over a month. I still do not make great money (probably the most has been $3 an hour). We did have a hiring freeze so that may be the reason they have been slow getting back to people who had taken the tests.
I also applied for ChaCha and was not accepted, but passed the kgb_ tests with flying colors. Totally different types of tests. Let me rephrase that, I passed ChaCha's tests, I did not pass the simulator. kgb_'s simulator actually walks you through and gives tips while you are doing it.
I have now become an approver and I "grade" others work. I do enjoy it and have learned so many things. I only do this for extra money as I do not think I could get so fast that I could actually make a living at it.
