A technical point, three questions commonly asked by interviewers:

1. What is xxx?
2. What are the advantages and disadvantages of xxx?
3. What are the xxx applications and usage scenarios?

BTW: We strongly urge everyone to register for ChatGPT, which can be used to improve interview questions. At present, some of the content is a little out of date. It will be a long time since I joined a new company and I won’t have time to update it. Please refer to it for reference. ?
