Please list some of the typical errors made by video game developers while programming a new game.

No one is perfect, and everyone makes a mistake or fails sometime during their career. Admitting this to the interviewer will demonstrate both your honesty and humility. When responding to a question about mistakes are failures, always emphasize the lessons you learned and how these have contributed to your skills and experience as a video game developer.

"During my career, I've either made some mistakes or witnessed all the developers making them. Fortunately, I always learn from both my mistakes than those made by others and am therefore unlikely to repeat them. Some of the common coding mistakes I've encountered during my career include:

Undeclared functions
Extra Semicolons
Undeclared Variables
Uninitialized Variables
Setting a variable to an uninitialized value
Overstepping array boundaries
Checking equality using a single equal sign"
