For a while, many friends left a message below my Zhihu saying that the Chinese New Year is coming soon. After the Chinese New Year, it will be "Golden Three Silver Four". I want to review a wave during this period. Do you have any good review suggestions and reviews? Plan?
Thinking about it, if I put forward targeted suggestions, it would be helpful to their review. However, I don't know the situation of these friends in Zhihu, or where the weak areas of these friends are? Can not give the corresponding review method. After several considerations, I decided to organize an Android mid-level and senior interview notes.

to sum up
In fact, the entire interview process is a process of constantly recognizing ourselves, so self-mind is the most important. We should treat the interview as a process of learning and growth. The results most people can get are directly linked to our past efforts. , So never complain about anything. Our current situation today is negative, saying that we are paying for the choices in the past. If we are positive, we must thank the Sao Nian who has worked hard.
