In the testing industry, one thing reigns supreme: You are replaceable.
There are many, many people out there that think that game testing is an amazing job. The sort of job where you get to sit around and play games all day. That’s not true at all. Playing games will get you fired. And every year, a new bunch of people graduate from high school that have this same thought in their head. “Man, I’d LOVE to get paid to play games all day!” This causes a huge pool of testers with a minimal amount of seats.
So what happens when a company has about 300 seats and 1,000 people banging on the door to get hired? They start throwing testers at the wall and seeing what sticks. I have seen entire teams get called into a conference room on Friday just to have them all walking out dejected… and replaced on Monday with an entirely new team.
The upside to this, however, is if a tester ever makes it to a position in a company above the standard tester, their position is a bit more secure (though not much), usually comes with some form of training, and it looks good on a resume. Mainly because it means you know how to shower daily.
