A few days ago, my friend vomited bitterness to me, and this wave of interviews hit him again, and he has been a software tester for nearly 6 years. . . In order to enter a big factory, I also spent a lot of time and energy on interview preparation, and I also did a lot of questions. But after doing too many questions, I have doubts about life. I don’t know if these questions can be used in future work. If I just write questions for interviews, is it a waste of life?
