I've recently signed up for a few CPA networks such as NeverBlue, COPEAC, and Hydra. Hydra has been the first one to respond to my application and has requested that I call for a phone interview. So my question to you guys is what can I expect from Hydra? I have a weight loss niche site so I will be focusing on health related leads first. Do they a good amount of weight loss leads such as acai berry? Also, I've only tried to contact my affiliate rep once and she did not answer but I have a question about the interview process. The only thing that I am concerned about is what types of questions they ask. Is is just related to how you will be promoting their offers or do they ask about your age, location, etc.? All responses are much appreciated.
