Phone Screening Initial Informative Interview with GM & Supervisor Interview with GM and CEO

Super unprofessional. Received a phone call from their head of HR. This is clearly her first HR/Recruiting role. She asked me questions while she was sitting outside. Very difficult to hear her and made me feel like she was doing me a favor by talking to me. Then she told me I'd hear back with next steps and that i would have to do a case study but she never gave me a date. All of a sudden I receive an email for an in person interview with no mention of a case study. Less than 12 hours before my interview I receive an automated rejection that they decided to move forward with another candidate. Super unprofessional experience.
