Sanofi Financial Controller interview questions

My initial communication was through my network. They did invite me for an interview via e-mail first. The first interview was with HR Officer and CFO (face to face). The second interview was with Senior Controller and Controlling Manager. This one was more technical based. They tried to understand the level of my knowledge and my ability to succeed the requirements of the position. The last interview was a group/panel one. Before the interview, they sent me a case and a few specific operational questions and I did prepare an power point presentation and sent it in advance. There were Controlling Manager, Senior Controller, HR Director and CFO. I believe it is very important to be relax but at the same time self-confident. The first impression and your attitude are also very important points.
