Here are some things you need to know about Citadel:

• I applied to work for them over 10 years ago. They called up my current manager at the time and talked to him about me (without asking me). I was a little clueless about this at the time, even though my manager hinted at it. If I had been more perceptive, I would have realized what they did and not gone in for the interview.

  So, if you decide to apply and are working full time somewhere, you should ask them not to contact your current employer until after there is an offer. But, I'm not even sure they would agree to this. So, I recommend avoiding the place simply because of this.

• The second thing that you need to be aware of is that the company cuts 10% of its "worst" employees at the end of each year. The head of the firm likes to experiment with social Darwinism, and this is one of the policies.

  It is not hard to see that "worst employees" turns into a very nasty game of political survival. I doubt if I would have been around that long since I tend to speak truth to power.

  I can see working here as a contractor if the pay is adequate.

Mostly object-oriented C++ questions.

They asked me to write a function for the add operator.
