There was a brief phone screen and then I had an hour long interview with two different people. They were not very difficult questions. I then didn't hear anything back even after contacting HR several times.

Initially spoke with the recruiter. That process was fine. On the day of the interview I was ghosted by the supervisors. Completely unprofessional and nobody reached out to me. If this is how prospective employees are being treated I can't imagine working at their company or how they treat clients. Apply for another Fintech company, clearly this company will not be around in the next 25 years with their lack of effort and unprofessionalism.
