Signify Proposal Manager interview questions

Easy first interview by phone with the HR, second on Skype. General Question about my background. Informal and nice recruiter. Second round more technical. Second interview with HR and 2 managers. Again informal but questions more related to the position.

One first interview with HR, discussing CV, motivations. Then another interview with 3 persons: global HR, and 2 others that would be n+1 or n+2 level. Plus I was asked to write a short paper as a test in 7 days. They did not reply to me, I guess that's a no but an email would have been nice after the time we all dedicated to the process. Also, the reason why I was not selected would be of great help.
