Optimy Client Service Manager interview questions

I passed the three steps of their interview - the first on Skype, the second with a timed test via email about their software guide, and the third in person, with two employees and the CEO. During the (quite tough) interview, in English and French, they suddenly proposed me another job position (as a Copywriter and Translator) they had opened, which could have possibly better matched with my profile. I was ill at ease, I didn't expect it, but they insisted I should think about it and give them my sincere decision by email after the weekend: they claimed they only wanted motivated, convinced and passionate people working at Optimy. When I finally took my decision (Copywriter) and communicated it to them, they literally disappeared, and three weeks later, an anonymous email in English informed me that my "application" (which one of the two?!) had been rejected for no further consideration.
