Domande di colloquio presso Virtual Access

Asked to show up on site for a first interview. It was an hour out of my way but OK, what ever. Entered the building and was brought to a room with a laptop that had no internet connection and 3 pieces of paper of which interview questions were printed out on. I was then told to answer the questions in whatever language I want and left in the room on my own beside the sign that says to not leave visitors in rooms on their own. Interesting, anyways. The laptop I was to use had no internet connection, interpreters or compilers as far as I could see so I couldn't run or test anything I wrote. The questions were mostly math questions that were completely unrelated to how good you are at software development and more representative of your skills as a mathematician. Once done I had to stick my head out the room and call someone over. At that point I expected a conversation about the decisions I made programming or a general conversation about the company and my background. Nope. None of that. I was then told I was done and that I could leave. I'm relatively confident that nothing I wrote was looked over by anybody so I don't particularly care if they ever get back to me with an offer or not. I would have preferred this being done over the internet so I didn't have to travel for 2 hours to have an hour of my time wasted like this.
