Very pleasant interview immediately with my 1st superior and HR specialist. It last 2 hours and was an usual conversation going through my CV focused only on positions that were related to the job I applied for. I found out everything of my supposed job position. 2nd interview included Finance director and the conversation was based on the case study (also 2 hours). If you are in the business you definitely know how to answer this questions in the small test and by answering those questions you show your professional knowledge and share ideas. That was the most important part of the recruiting process.
