Interesting. In the business world, depending upon the consultant's credentials it's approximately $100/per hour with a minimum of 4 - 5 hours guaranteed plus any expenses incurred on the phone. Pre-Covid you were paid mileage, tolls, parking and lunch as well. That said, you are not consulting this person per se, simply interviewing them. So, really very little leg-work on their part to do any pre-work. I think you made the right move passing. The person you could have interviewed though made a dumb decision because exposure at any age or level, is the name of the game in the entertainment business.
