Worst company management and interview process I have ever seen. Very unprofessional behavior from the HR team. I have attended three round of interview and cleared but at the time of last round just 2 minute before HR cancelled the interview after that did not get and call and email from HR team. At least management should understand about the value of the candidate's time. If you don't have proper vacancy or budget then don't take many round of interview and inform to candidate before cancel the interview.
