Perguntas de entrevista de vagas de Software Developer In Test da empresa Dayforce

I was contacted to do an initial interview with someone from HR to give a brief overview of myself. At the end of the interview (which I thought I did quite well), I was told by the interviewer (HR person) that they would like me to give a suitable date so I can proceed to the next stage, which would be an interview with senior developers. I gave a list of post dates, and the interviewer told me they will come back to me in a couple of days to confirm the actual date. It's been a month and a half now, and I have been ghosted.
