They initially communicated through mail and I went through audio and video interviews, about 6 rounds and even after being told that I have cleared all the rounds. The position got canceled in the end and they never even bothered me to inform this. I kept trying to contact them and this went on for about a month more and finally they sent a mail that I couldn't make it though I still have no clue what went wrong even when I was told that I have cleared all rounds.
