Aon Cat Modeler interview questions

They called me specifically to check if i was interested in that position (they had my info and I've already passed the interview process since I applied for a similar position last year), asking me to wait a couple of weeks to officially announce it in the web and continue with the process. They had me waiting for weeks and at the end not even the person who interviewed me nor the HR manager replied any of my emails. Still a great unknown of what happened since the position is still open.
