The pressure of competition in the IT industry is increasing, especially in the Android development industry. But many Android programmers repeat CRUD every day, wandering in place!
At the beginning of this year, you wanted to change the status quo, so you swiped a lot of interview questions on the Internet, and after forcibly wrote down, you started to participate in the interview! But you find that interviews are getting harder and harder now.
I submitted 10 resumes, and only one offered an interview invitation. Interviewers don’t ask about the content of their work. They ask about terms that have not been heard very much. **What are hybrids, NDKs, and rarely asked memorized questions, but they don’t follow the rules of the card questioning principle. It comes up as a series of questions. Cannon, caught you off guard! **I even suspected that I was a fake programmer, feeling that I didn't understand anything!
Everyone has become more and more impetuous, and owes too much technical debt. When it comes to the interview, they start to go to the doctor in a hurry, blindly learn some interview questions for the interview, or accept various technical groups/blogs /Information website about technology/About the bombardment of life, but can not accumulate solid and in-depth technical knowledge or application experience. If this continues, it will only become more and more anxious and there will be no real technological improvement.

Development requires a certain foundation. I started to enter the Android business in 2008. During this period, I experienced the heyday of Android, and the so-called Android "cold." Of course, there is also an unspeakable sadness in the middle. Looking at my friends and colleagues one by one, I switched to the front end and changed industries. In fact, my heart was hesitant at the time, but I persisted. This epidemic is a good opportunity. The big waves wash away the sand, and the fittest survives. Wait, maybe you will be waiting for the next wave of gold.
This is some information I have accumulated over the past 10 years in this industry. If I still want to continue in this industry, or if I plan to change jobs now, I can **Private Message [Learning]** I am willing to share the information with everyone for free.
