The most unpleasant interview experience ever

Although the shop looked nice I had an awful experience.

I went for an interview yesterday and met the most unpleasant and disrespectful guy ever. On arrival, I greeted as one should, and he didn't even bother greeting back....He was eating during the interview, chewing loud and aggressively , chatted with staff while I spoke even walked away for a while.Never once made eye contact. I couldn't believe or understand what was happening as I've encountered someone so rude before. When I was done he just noded and pointed to the the exit. Although I was way to over qualified for the role, as the post advertised was really confusing. A bit of manners and respect never killed anyone.Kurt was so rude, unpleasant, and conducted himself in the worst manner I've ever seen from an interviewer or even person . You don't have to be all jolly or friendly but decency wouldn't kill you.
