If it wasn't for being abandoned by my girlfriend, I guess I haven't woken up yet. A college student, who entered a software company in Hunan through school recruitment in 2019, and has worked in CRUD for nearly 3 years. At the beginning of this year, I felt that I could not go on like this. Staying in a comfortable environment for a long time will make a person fall! And I have been doing CRUD in a company for three years, which has made me not enterprising, and my girlfriend who I talked to for 2 years broke up with me because of my mentality and salary. So, I decided to change the status quo and focus on this year's gold three silver four!
When I first started preparing, I was blinded. Three years of CRUD did not make any progress in my technology, and only my age improved...
No way, I found my old brother in Tencent, as his little old watch, after he learned about my situation (almost the beginning of Java basics), he directly threw me a network disk and said: "Go ahead. , here's everything you need, don't come to me, I'm ashamed!".
There is a complete set of PDF documents required for Java interviews. After reading it, I will kneel to my brother. Now the interview is stable
The content covered by this set of documents is really too comprehensive, whether it is advanced growth or dealing with interviews, it is more than enough. There are a total of millions of words, and it is definitely not realistic to show them all. In order not to affect everyone's reading experience, only part of the content is shown, and I hope everyone will be happy.
