I had the worst interview experience on Friday

I’ve been recently interviewing at a well known company the past week. I’ve already completed a screening call, teams meeting and met the director on Friday. The recruiter has been lovely and extremely helpful explaining the role. The director on the other hand couldn’t be any more ignorant or smug if he tried. He decided to bring his lunch into the interview and eat it in front of me, he left the room for a minute to grab a notepad and when he came back in I was on my phone texting whilst waiting and he told me they have a policy of no phones on the desk if I work there. When I asked him what the work culture is like he said it’s good because they go for drinks after work on a Friday and then decided to ask me do I drugs after that and was shocked that I don’t. He also asked do I prefer him or the recruiter that I was already interviewing with and when my girlfriend phoned me during the interview he told me to silence my phone. It seemed a good opportunity until I met such a loser.
