Pretty straightforward. Asked me regarding my project experiences - a game I made. He asked me about a comment I made regarding how I learned how to implement the tick on my resume to measure every moment of the game. I answered.
He then asked about my internship etc.
Then he asked a programming question, how to implement a function (in any language) that returned in index of a fibonacci sequence. Very straightforward and easy, however, I had difficulty understanding what he wanted at first. After thinking I understood what he wanted I made an assumption (that the fibonacci array was passed in) but evidently it was not. When I gave my code he asked where my array was passed in. I responded by saying I assumed it was passed in. He condescendingly responded by saying with an amusing facial expression "Umm... No I didn't...". Was it inappropriate? Probably, I wasn't phased though. I recognized I had difficulty figuring out exactly what he wanted and what was passed into the function. Regardless I fixed it and he checked and the function turned out correct.
We then had 3 minutes left and he asked my if I had any questions. I thought for about five seconds and said I didn't, I was familiar with the company and my role. He responded indignantly and this time a bit rudely stating: "Well if you have no more questions we should just end this interview right now" and smirking.
It was amusing, I again wasn't phased I just didn't quite understand why he was attempting to be such a jerk. Hence, I asked questions I didn't really care about to get him to lighten up again. The note we ended was a bit better.
