I had one interview with the SVP and one assignment, assigned the same day I interviewed. The assignment consisted of developing a brand target audience, developing messaging for said audience, developing a list of 10+ keywords to target for SEO content, and a two-week editorial content calendar for the brand. I submitted the assignment on Friday at noon, on Monday at 11 received a rejection email 'Which was a very difficult decision to make, considering the caliber of my work.' When I asked for feedback on why I wasn't chosen to move forward, I was ghosted. 99% chance they're using these assignments to get a marketing strategy for free. Don't waste your time.
