When I went to the Internet to read the blog, I found a few better pictures, here is a convenient way to understand it
The article is explained from the perspective of pure interview, so there are many details that are not foreshadowed.
In view of the feedback of many students did not understand the “online interviewers” series, I did write articles related to the basic knowledge explained, but some students just do not like to read.
In order to make you have a better experience, I have also found the basic articles (important knowledge points I have also sorted out e-books, such as multi-threading, collection, Spring and other interview tests have already been converted to PDF format).
I’m gonna upload these to a disk, so you can download them if you want. You don’t want to fuck for nothing, do you? Likes and retweets are free.
