Eh I just took an examination for a Bloomberg job, and I'll tell you,
I'm so frustrated with myself. The examine didn't cover anything
particularly advanced, but it hammered on a bunch of stuff that are like
puzzles needing sure knowledge of operator precedence, and type
casting. The C++ end had a lot of questions on "virtual", something I'm
just not familiar with yet, const and static values.
I felt like such an idiot.
