first round was telephonic, once i cleared it, after 10 days they called me second round of interview in person. 2 rounds of interviews there.went on very well. Since the manager was busy, they told me that they will schedule it on another day and never got back.

Phone and 5 rounds of face-face and followed by hiring manager. This company is totally unprofessional in hiring and communicating with candidates. They open up a role for sometime and keep it on hold for sometime and re-open again. So, for candidates there is no assurance that job is really open.
