This will be one of the easiest job interviews you will ever go on. They will be selling you the position more than anything. If they need to fill a spot they will offer you the job that same at. This is a huge red flag. It doesn't matter if you have prior sales experience or not. You might not even know anything about fitness, and they don't even care. If you are in somewhat decent shape they will hire you on the spot. They will lie to you and promise you all this income potential, and none of it is true. Also no background check at all.
