Not anymore. When I was fresh out of school and looking for a job, I would've. But I'd have taken any job back then.
Game testing is a horrible profession. It's underpaid and holds zero respect among developers. And no it's not about playing games early. Most of the time you have to playtest certain situations over and over again, often without context. Trying to produce or re-produce bugs, or check if certain changes work or not. It's a highly repetitive and boring job, that will probably make you hate games before long if done as a profession.
I'd love to play through unreleased but comlpeted games early too, but unfortunately being a game tester is not just about that. By the time you get a finished game in your hands, you are hating every inch of that game.
