I got a call to let me know I've been shortlisted and my interview would be scheduled soon. The next day, I followed up asking what date/time will it be conducted on? I didn't get any response but all of a sudden I get a call the next morning asking me to interview within the next hour. I explained it to them that I was not available that day and no prior information was given to me about the interview in advance. I asked them to simply schedule it for whenever but at least let me know in advance. To my surprise, I was ghosted by the HR completely.
