Weber Shandwick Account Manager, Media Relations interview questions

The process started out very normal with an email and initial phone interview. The same day I received notice I would be speaking with an EVP in the next round. The phone call began well but turned unprofessional very quickly. In the middle of conversation, he puts me on hold for several minutes and returns with a completely different attitude. He cuts me short, shows zero interest and wouldn't allow me to ask questions. Not sure what happened while I was on hold. Overall a very negative experience and very unprofessional executive.
