You passed the tests. Very likely, you'll be offered the job.
At this point for the branch (and corporate) its a numbers game. Your sales approach / emotional IQ is similar to an 'ideal' rep. So, it makes sense for them to pay you around $60k and minimal comission for the first three years- then transition you to a growth plan where you take home the same money for another three years (since you pay your own expenses).
The great majority of reps will make progress during this time and 'pay' for their own salaries easily. If they choose to leave during this time the accounts they've converted will be given to current reps.
For those who stay the course and eventually hit the $2mm+ mark they have 'paid' Patterson a great deal for the opportunity (and hopefully will not get a new branch manager who 'manages them out', reallocates their accounts to existing reps, and hires new reps to continue the cycle).
There are as many good stories as bad. Close for a ride-along with a rep on the base plan. During the course of eight hours, ask specefic questions about the manager, turnover among new reps, the divide between the old / new reps, increase in avg daily sales over time, what they know now that they wish they had known before taking the position, etc.
Continue to take the time to really understand the opportunity.
