Robinhood Software Developer interview questions

Contacted by recruiter for phone screen. After phone screen did the Codesignal coding interview. After completing 4 questions, received a rejection letter which is phrase politely saying that I am not considered for the role for this season, and they are not allowed to provide feedback. Just typical Ghosting in the industry, I am currently an engineer at a FAANG company, I get paid $200 an hour, if you are not planning on hiring don't waste my time. I spent 2 hours that, this interview alone cost me $400. Covid is not the biggest pandemic in the industry, its ghosting by these recruiters. My time is precious, do you want to pay recruiters to ghost me. Robinhood is a bad trading platform, there is so many ways I can improve it, but I don't want to because you chose to ghost me.
