As enticing as this company sounds, I would advise staying away from them.
The company is difficult to get information from (requirements, etc.). You can expect emails, voicemails and other such to go unanswered.
Furthermore, they have most recently begun a quality control program that is often inaccurate, but almost impossible to get corrected, and you will be penalized.
It's an odd situation where new examiners who come on board are treated very well at the beginning, but their customer service to you slacks off dramatically.
I wish I didn't have to be so negative. These folks are pleasant to deal with, but the company itself is run badly.
They do pay more than some of the other companies, but the headaches are not worth it.
