Preface

As a programmer, if you still don’t know anything in the face of new knowledge and new technology, and you still have a legacy of more than ten years ago, then you must be behind in knowledge and technology. If you fail to enter the management level, then you It will definitely be shot on the beach by the back waves of the Yangtze River.

Many programmers who are advancing with the times and good at learning are still the backbone of the industry. This just means that today's world has traveled all over the world with a single trick, and the era of life-long eating has passed. A person must live and learn before he can walk in the world.

In my spare time at work, I will also turn over the interview questions of Dachang, so that I can always maintain the interview skills, and at the same time, I can understand the needs of Dachang for technology in order to prepare for emergencies, "Born in trouble, died in peace "The ancients don't deceive me.

Let me share with you a systematic growth and advancement route that I have summarized over the years of my own work, and share it for your reference.
