My first round of interview was for 1 hour and it was on basic technical and scenario based questions for data architecture and models. It went smooth. After that no response from HR for more than 1 week, and then HR reached and said next round need to be scheduled. Then HR said that he already confirmed me 1 week back, he was having no clue if he did, then he checked and said they are good and will send schedule mail invite same day. Next day I followed up with them and next day they said they are looking to schedule soon, but no mail invite was sent. And after that they just vanished, ghosted me. At least have the decency to confirm that they can't proceed or position is filled or whatever is your reason. Never going to appear for there interview again.
