Golden Scent interview questions

First, someone from HR approached me via LinkedIn and she was just chatting with me that they are looking for Digital Head and the JD not ready yet and we need to have the interview with the CCO, we set a time (all via LinkedIn messages, no single call) and I went on time and wait for 30 mins for the CCO in the reception and I found the HR apologized that the CCO has an urgent call and she will interview me until he finishes the call!! She was completely clueless and can't ask any reasonable question and seems that she is not prepared, the interview lasts for 1 hour, and still the job details not revealed yet. While I was leaving the office I found the CCO talking to someone in the reception!! This company totally unprofessional and a waste of time, I don't recommend anyone to even respond to their messages on LinkedIn.
