Domande di colloquio presso swissQuant

I had one interview in their office last year. Their solution seems a bit complex but overall explanations from the interviewer was ok. Interview continues and exchanges seems to be going well/ok but they never sent me an answer about refusing me or choosing someone else for the position. Tried 1-2 followups emails and 1 call but never had a reply. I think it was a little bit disrespectful.
