Thank you all. The issue is resolved by a phone call followed by emails. It was a communication issue.

Before the visit, my same edu email got replied in few hours -- after the visit they blocked me like a spam person? Unbelievable if it had been the case...

Thank you all for the reply. I think my case is different from the other question because I received no replies at all -- I would say this is more an etiquette issue rather than university bureaucracy. How come the dept/search chairs not even care replying emails... Phone call is sure my next todo.

Any updates on this? What happened to the position, did someone get hired? This might be helpful to future readers on the implications of a TT job re-posting.
