Game development, with C# as the primary programming language.

The first interview round was an online programming test, and there was plenty of time. I made one mistake at the time and mentioned that I wasn't familiar with JavaScript, but I still passed. At the on-site interview, there was a whiteboard question involving a sorting algorithm. After I finished writing it, they asked whether there were any other approaches. I changed it to a recursive solution and passed. Because I was applying to the company for game development and it was my first job search, I said I wanted to think about it after not receiving a verbal offer, and there was no follow-up.

P.S. You couldn't see the office when entering the company, so it felt very strange.

Game development; the office was hidden and the atmosphere was strange.
