Confetti interview questions

I met with their Interim VP of marketing after a phone screening. His main focus was an "attribution challenge". The whole interview was like him trying to get free consulting. I submitted a lengthy document on his attribution problems, he wrote back with a positive response. Shortly after his response I heard back from the recruiter saying Confetti would not be moving forward with my candidacy.

The interviewer was adamant about staying in the companies salary range at the low end which is far below market value. This company doesn't pay its talent and will continue to hire C level players instead of A level.
