2、 My feelings:  

1. If you want to be close to a large factory, you should make full preparations and brush questions in advance. For social recruitment, we should not only brush the questions, but also prepare the highlights of the project and work experience. School enrollment should be prepared in advance. School enrollment is a great opportunity to be close to big factories.

2,Many interviews are similar,For example: JVM principle, concurrency, SQL optimization skills, data structure algorithm... Many companies will ask in the interview.

3. When new parts or new subsidiaries of some large companies start to recruit people, it won't be too difficult at that time. Pay more attention. It's not so easy for a company to recruit the right person. If the technology is good, it's good to make an offer. Last year I interviewed 10 companies and got 10 offers.

I know what the company needs now!

4. Big factories are really not so difficult to enter now.

A lot of interview questions have been prepared:

1,❤️ liver failure! Sorted out the spring interview [including answers] for a week and hanged the Java interviewer [suggestions collection]! ❤️

2,❤️ When the liver is over, master the data structure and algorithm one day, interview questions, hang the interviewer, and suggest collecting ❤️

3,MySQL interview encyclopedia, after reading it, you can hang and beat the interviewer!!!
