First interview with HR by telephone, after two weeks she called me to schedule an interview with a Manager by phone, two weeks after she call me to let me know the interview was wonderful , she schedule another interview with another manager in USA she ask me my availabilities, no feedback, after a month she send me a email with the interview scheduler, I did the interview with another manager because that was supposed to conduct the interview had an emergency, after another month, she just sent me a email with another interview she say this will be the last interview, after two weeks HR sent me email to informed that the decision taken by another candidate. They wasted a lot of my time and don't appear to have their act together.
