I've done the job. The pay is mediocre. You don't need a degree or specific experience, but you do need some sort of experience showing that you can handle stress. You also have to deal with the stress of the application process, which is intense. If you can't deal with those stressors, you can't deal with the job, because it's all boredom, boredom, boredom, STRESS, boredom, STRESS, boredom, boredom....
There's a reason few people stay in the job long despite how hard it is to get.
