I applied online and an HR manager from London contacted me by email. First interview was super easy with HR, second one with two different managers from the team speaking about my past experience and my expectations for the future. Third interview was at Dublin Office with 2 managers: a mock call very useful with a manager that help me to be relaxed, and 1 to1 interview with a unfriendly hiring manager. This interview has been the worst in my life: disconnected questions and bad attitude from the manager. Last interview was on Skype with the head of sales from USA, who asked me about my background and some situational questions. Feedback arrived after many follow ups, with an automatic mail (as the one that normally send you at first step).
