The process started promissing. The recruiter who contacted me was involved, kept in contact throughout the process with prompt responses to my messages. The scheduling of the technical interview was quite chaotic but I got over that. The next day after the technical interview I got an offer I rejected quite quicky as it was much lower than I expected. After receiving my rejection email, I got a request from another recruiter to have a phone call to discuss my reasons. I mentioned on the phone that I speak a little bit of French and instantly he switched to talking in French, I managed to understand 50% of his speech about how great the company is and how they never underestimated their employees. After finishing his speech, I eventually managed to say something. When I told him I've seen better offers in Luxembourg and this is why I rejected the offer I got an "OK bye" mid-sentence. Quite impolite.
