Genesys Associate Software Developer Backend interview questions

Very very unprofessional, got hard ghosted. HR reached out and scheduled a quick call to go over some basic information, said a second technical interview with the manager would be scheduled next week, waited for a whole week and nothing happened. Sent several follow-up emails, no replies. Called the HR, they sounded like the first conversation never even happened, said they would get back to me after checking, never did. Checked the portal yesterday and saw the application status changed to rejected but the position is still up. What a total waste of time...
