two to three rounds. met with HR first. extensive with many questions pounded back to back. had interview on a tough day and it definitely did not help that she was so aggressive with the questioning, unlike any interview I had ever had before. i knew interview did not go as well as I would have liked, but was told that I would be hearing back early the next week. I didn't hear back for around 3 weeks which was bothersome, however understandable given the quantity of applicants that they have.
