Extremely unprofessional. I applied through the website and gotten a reply on Monday. I then went through their portal to get a HR interview slot as they had sent to me. And I booked for the next day Tuesday interview with the HR. On Tuesday itself, 30mins before the intended interview, the HR shifted it to the following day. It was shifted to Wednesday. On Wednesday itself, 1 hour before the scheduled time, they cancelled the interview and said they are no longer proceeding with the interview. This highly unprofessional. I have never gotten such a terrible experience elsewhere.
