America's Job Network interview questions

I was contacted by them to determine if I might be interested in the position. I was asked a series of probing question on background. I was sent internet links to review and to call on completion of review. I then met an individual who showed me the office and employees working (nice facility). We then spoke for an hour and concluded that I would be meeting with another individual to get their input. Still unclear is the commission payments and how they are paid. I was told 12-20% but of what wasn't made clear. This is a sales job that takes multiple contacts with the client who must pay from $5500 to 10,000 based on services to be provided. I will have my next meeting and provide feedback
