Want to stand out in interviews and jobs? Want to quickly master the core basic knowledge points of software testing in the shortest possible time? Want to be an excellent software test engineer? This article can help you!
At present, it is the peak season for job hunting. Many students can talk about some new technical terms, but they do not have a thorough understanding of some core principles, especially some core basic knowledge points of testing. As the so-called high-rise buildings rise from the ground, only by firmly grasping the foundation can we go further, and can quickly master the constantly updated technology, and at the same time stand out in interviews and work!
I only selected a few good ones for the interview questions below, and the rest are too many to finish, so I have organized them into notes. If you want notes, you can follow me on the small card at the end of the article to collect them yourself. In addition, I have compiled and collected the interview knowledge points of more than 20 years of companies, and shared the core knowledge points of various tests with everyone for free. The following are only some screenshots. All interview questions are not static, especially for first-line manufacturers. The following interview questions are just for reference. The most important thing is to increase your knowledge reserves and be prepared.
It mainly includes test theory basis, Linux basis, MySQL basis, Web automation test, interface test, App automation test, test tools, Python foundation, Selenium, performance test, security test, test development and other special technical points . The interview questions summarized by the factory, many friends have already won offers from many big factories by relying on this PDF, today I will summarize and share it with everyone!
