Preface
Papa Ma summed up a sentence: quitting a job, either because the money is not available, or because he is wronged.
I did an analysis of my job-hopping experience this time, hoping to help those friends who want to change jobs.
Many friends want to change jobs, but the understanding of "changing jobs" may be limited to writing resumes, submitting resumes, and interviews. Before quitting, I thought so too.
At that time, the work was not going well, my professional skills did not play well, and the company could not give much prospects for development, so I planned to change jobs.
I saw a good listed company in the industry recruiting this position, so I sent a resume. I felt good after the interview, but I refused because the salary did not meet expectations.
After careful thinking, I found that I was too rushed to prepare, or not prepared at all. I wrote a resume roughly and went there without adequate preparation before the interview. In the interview, some details of the project cannot be answered, and many knowledge points are not answered well, which may make the interviewer feel at an ordinary level.
In the next few months, I began to look up various job-hopping and interview-related materials, and at the same time organized the key points according to the plan, sorted out the learning path, and gradually reviewed.

There are a lot of materials for learning Android on the Internet, but if the knowledge learned is not structured, and when you encounter problems, you just taste it and stop studying it in depth, then it is difficult to achieve real technological improvement. I hope that this systematic technical system will provide you with a direction reference.
