Interview is actually a very interesting thing. In the interview, we like The Eight Immortals Crossing the Sea Gexianshentong, only to get the favor of the interviewer.

A lot of people think the recruitment process should be changed, but I personally, I think the stage should not have much change, so we can only adapt to the recruitment model.

Looking back on my career, I have been self alone, and also some of the special talented people worked together, had solved a number of very serious technical problems, have seen some of the illustrious technology companies. Recently, I and my team occasionally talk about my experiences, the results of the talk is that we should know some of the principles of encoding. This is not a rule, and it's not a guide. They are just some of the principles that I need to pay attention to when I write and run the code.
This is almost natural for me. I almost became a programmer by self-study.
