Gamasutra writes: "Programmer tests are generally one of the most loathed parts of the interview process, on both sides. But every game programmer interview should include some kind of test to make sure the applicant can walk the walk as well as talk the talk.
There are a few types of tests a programming applicant can expect to see. The first is a pre-interview test, which may be given by email and may either come before or in conjunction with a phone interview or screening.
The second is an in-house test, which is given as part of the face-to-face interview and is completed on the spot".
