I went through this process end of March/beginning of April 2021. I was ghosted after 3 rounds and after being told I was the "top candidate" multiple times by the internal recruiter. A complete waste of my time and energy. Rd. 1 - Generic recruiter screen. Rd. 2 - 1hr interview with the hiring manager including an off-the-cuff case study presentation. I rly liked her vibe, but she seemed stressed. I was unsure what to make of it. Rd. 2.5 - Easy take-home design challenge (albeit with minimal, confusing directions). Rd. 3 - 1hr Interview with 2 UX designers on the team. Both seemed like genuinely nice people, but I left feeling unsure of their ability, knowledge of design methods, and understanding of process. All rounds went very well and I feel gaslighted by the experience. Thankfully, I got an offer from a much better company for a role at a higher seniority level a few weeks later. Unless you're desperate for a job (as was I), I'd suggest passing on Blue Fountain.
