Robinhood Learning And Development Specialist interview questions

This place is shady. I had a phone interview with a recruiter, at the end of which they scheduled a second interview with the hiring manager. The second interview was scheduled two days later. The day of the second interview the manager never called. I e-mailed the recruiter after 15 minutes asking if we needed to reschedule the interview, and never heard back. Never before have I been ghosted by an interviewer. Bizarre experience and entirely unprofessional.
