This site features a collection of common technical interview questions gathered by a group of programmers who have been through, and given, lots of technical interviews. There is an emphasis on C++ and game programming technical interviews, but most of the questions are relevant to any technical interview.
Rate Thyself

Rate your C++ skills on a scale of 1 to 10. (This is a VERY common question for C++ programmers, and definitely one that needs to be thought about in advance. Obviously you don’t want to rate yourself too low, but rating yourself very high may be asking for trouble unless you can handle it!)

string this Reverse

Given a null-terminated string, reverse the words within it (assume that words are separated by one or more spaces). Now do it in-place.

void reverseWords(char *aString)
{
Largest Sum of Contiguous Integers

Write a function the returns the largest sum of contiguous integers in an array. For example, if the input is (-5, 2, 3, -3, 0, 5, -15), the largest sum is 7.

int LargestContiguousSum(int*iArray, int len)

Programming Interviews Exposed
This book teaches you critical interviewing skills such as how to ask effective questions, how to best approach a problem, and what to do when you get stuck. Integrated throughout the book are problems taken from real interviews at top computer companies, followed by an in-depth analysis and explanation of the thought process leading to solutions.
Copying vs. Assignment

What is the difference between a copy constructor and an overloaded assignment operator?

Private Constructors

What happens if you declare the only constructor in a class as private? Give an example of why you might want to do this.
