My friend complained to me a few days ago, and this wave of interviews hit him again. He has been a software tester for almost 6 years. . . In order to get into a big factory, I spent a lot of time and energy on interview preparation and answered a lot of questions. But after answering too many questions, I feel a little doubtful about my life. I wonder if these questions can be used in future work. Is it a waste of life if I only answer questions for interviews?
