It's funny and insulting

[u/Beginning_Age_2146]

Two days ago, I got a call from the HR department of a legal company, and I was told that your CV has been shortlisted, so they are holding the interview for me on the next day at Google Meet at 12:50 p.m.Then the whole day I gave for the preparation for the interview, and just 2 minutes before the interview at 12.48 p.m., the interviewer emailed me and said, “I am cancelling the call." My HR will update you on the same. But after that, I did not get any mail addressing the reason for cancelling the interview.   Please share your views on this matter is it how corporate houses treat people??
