Is it too late to switch to software testing at the age of 30?

The greater the career change span, the more new knowledge you need to learn. The most important thing to change careers at the age of 30 is courage, because many people are afraid that doing some junior jobs at this age will be laughed at, and they are even more afraid of losing face because the salary after changing careers is not as good as the previous job.

The result of career change is unknown. You are not sure to make yourself 100% successful in changing careers, and you are even more afraid of facing the result of failure.

But what I want to tell you is that if an industry is depressed, its development prospects are not good, and the promotion space is limited, in this case, even if you are 30 years old, you should change careers decisively at the age of 35.

It is better to fight hard than to boil frogs in warm water and die.

It's not too late to learn software testing at the age of 30. Do what you want, and then stick to it.
