I applied as junior gameplay programmer at Sofia. They wrote me 2 weeks after my application and asked me to choose a date on which I could have taken a 4 hours test. I proposed a date and they said it was fine, then they forgot about me and contacted me only the day after, asking if I could have taken the test on that day.

In my opinion this was a very unprofessional behavior.

26 exercises (given as VS2012 project) on common algorithms, data structures, linear algebra, simple and advanced memory management, optimization of code, multithreading and C++ syntax.

4 hours of time (not enough if you miss a single argument).
