I can remember an interview I had that, at the time was quite bizarre, but in retrospect is quite funny. I was in my early twenties and had applied for a supervisory position at a medical management company.
I knew I had the skills necessary for the job and had prepared myself extensively for the interview at hand. I dressed in my best suit and arrived at the corporate offices to interview. I first met with the manager of the finance office. She was very pleasant and seemed very knowledgeable about the industry. I felt very at ease with her, and my responses flowed effortlessly. I kept thinking, "This is a piece of cake." She then advised me that she wanted me to meet with the CFO as well.
I took this as a good sign and enthusiastically introduced myself to him. His office was the typical executive office, complete with the black leather executive chair. He would ask me a question, and feeling confident, I would begin to answer. During the midst of my response, he would ask me another question. Again, I would begin to answer, and then he interrupted me again with yet another question. When I managed to answer a question completely, he sat back in his chair and sighed.
In my mind I kept thinking the interview was not going well. The CFO leaned back in his chair, adjusted his position by kicking his leg over the arm of his executive chair. I sat there flabbergasted; I didn't know whether to laugh or keep my composure. I chose the latter of the two.
