Property Meld Senior Software Engineer interview questions

HR person reached out with a link to schedule an interview. I schedule an appointment which was in 3 days. 30 mins before the interview she sends me an email about a schedule conflict, asking to reschedule to "Thursday afternoon". I reply affirmatively, asking to clarify specifically what time on Thursday. No response, no show, no call.. Very unprofessional and disrespectful of candidates time, don't waste any time applying here.
