Activision does a mass hiring every year for testers. 90% of the people hired will have a terrible work ethic, poor social skills, and poor communication skills. 5% will have all that plus poor hygiene, and the remaining 5% will be rockstar employees who take the job seriously.
Everyone is paid the same, so the worst tester makes as much as the best tester. Good testers are rewarded with more work and responsibility for no extra pay. This creates resentment, and bitterness which results in good employees leaving who will then be replaced by more bad employees. At times it feels like working in a job that is one part office and one part kindergarten as just trying to get the majority of your fellow employees to behave like adults can be a futile struggle.
All the profits go to the higher ups and they only raise tester pay if they absolute have to.
This is the job where dreams go to die.
Unless you're a kid looking for a summer job, avoid at all costs.
