As an IT student learning only C# and Java, I was asked very specific questions on c++ about micro optimizations, and binary operations (why i haven't learned that i still wonder, i had to self teach it)

Because of not being able to answer that i was denied that internship, because fuck your and wanting to learn as a student.

I litterally mastered all questions asked the day after the interview just out of spite. It were all concepts i easily understood but they valued their paper based interview more than actually giving me some code to work with.
