I went through the whole process to the final steps, including an interview with an executive - and was ghosted. Completely ghosted, several email follow-ups and I couldn't even get a "Thanks but no thanks" from the hiring manager, interview team, or recruiter.
This followed an ask for a 20-slide presentation (with no template provided), from scratch, to do in 72 hours over a weekend - which took approximately 12 hours worth of work. My gut instinct was to let them know my hourly consulting rate, but because I had such great interactions with the team, I relented and did it.
I wonder if they took my work for free after the presentation?
Anyway, I'm glad I saw this side of the company, and avoided making a career mistake.
