SkySoft-ATM interview questions

Passed first technical interview, passed second technical interview with team. They wanted a third interview, "a formality to meet in person and meet the team", which I did and obviously "passed". Or so I thought. The recruiting company who found me flew me to Geneva and back (4 planes in 2 days). They interviewed me technically again and more, introduced me to the team who showed me some project details, and showed me around. "Everything would go fast from now on", they said. Well, I never heard back from them ever since. And the recruiter who found me could not let me know any reason of that behavior either. Most unprofessional situation of my life.
