4 rounds. It took about 2 weeks or a bit more. Smooth and relaxed interviews, nice chats, but never got the response after that, even after a couple of emails to the sales director and the operations director and to HR. Very bad experience. Never happened to me to get to the final round of interviews for a manager role and receive no feedback. If it reflects the company culture and morale I guess it's better not to cooperate with them at all.
