The company has a new 20K test, which let me see what the real test ceiling is

Time:2021-12-30

Today’s morning meeting at work was a meeting ceremony for new people. I heard that a very powerful boss came. He left his last company and his salary has reached the medium level. Many people are curious. It shouldn’t be easy to get this salary. Sure enough, when I introduced myself, I was surprised to see what the real test ceiling is

Automated testing, test development and high concurrency came, which really surprised us. When we asked, it turned out that there was a contradiction with the leaders in the former company, and they couldn’t stay until they left. When they came to our company for an interview, the leaders took a fancy to him, asked some questions and passed him after chatting. If people have the ability, they are different and shine everywhere!!!

After chatting with him all night, I sorted out some knowledge and technology sharing of his testing career. I hope it can be of some help to you!
