I was contacted via e-mail by a Managing Consultant who got my CV from a recruiter. I was then invited for the 1st interview with a Manager in Paris. The interview was mostly about past experience, some fit and easy behavioral questions. It went very smoothly and subsequently, I was invited for another interview with 2 Managers (different than the first). Questions were easy and pretty much the same as the 1st interview (personality fit, past experience, expectations, some skillset questions) followed by talking about the projects and my future ambitions. In general, it was a very easy talk and they gave me a positive feedback and said they'd contact me to arrange a meeting with Partner for the last stage (fit, negotiations). Having no news 2 weeks later, I contacted them via e-mail, they replied and apologized and said they'll contact me soon. However, they never got back to me after that point, which I find very unprofessional.
