Vigeo Eiris interview questions

The company contacted me for an interview and we had it within two days of their initial contact. It was via skype with two people. When I finished that interview they said that I would be contacted by HR to have a second interview. However, this second interview was just to clarify that I would be working in Paris and to tell me that I got the job.

Pretty misleading job advertisement as it is published on Moody's website while the actual contract would be stipulated instead with Vigeo Eiris. Had three full round of interviews and reached the final stage: interviewers were pretty friendly and the case study (basically a vlookup excel exercise) was pretty easy. Reached the final stage and then received an automated email saying I was not selected. Asked for more information on where I could improve, but no response.
