Don’t get stuck in this office after the interview. I hope those were not people really looking for a job. I would not joke with unemployed looking for source of income.
I agree with your sentiment. However, the only thing that keeps me going as a job seeker is laughing/keeping humor instead of crying. I've had some unfunny things done to me in interviewing. This is funny! Bring on the funny as long as it lands me a job in a funny yet productive environment. Note, I would never want to see this CEO and his butt again, however. LOL.
