More and more people are talking about “the second half of mobile terminal”, “anxiety of Android development”, others are Shouting “technology is changing every day, learning is endless”, “Kotlin yesterday, Flutter today”. I actually think that if you’re skilled enough, you don’t have to worry too much about it.

Is mobile really in the second half? Not in my opinion, at best “Android technology exploration” entered the second half, and the overall market is still optimistic. BAT used to dominate, but in the past two years, more and more unicorns have emerged: Toutiao, Douyin, Pinduoduo, Kuaishou, Xiaopingsoti, etc. Their businesses are all on the mobile terminal, and they need to recruit more mobile terminal talents. If you look at the second half, it’s a lot of small startups exiting the market. It’s true that many entry-level engineers are losing their jobs, but it’s also a sign that the industry is becoming more regulated.

And it’s a good time to be an Android engineer. As the Internet sinks, it is clear whether users in the sinking market are more likely to use Android or iOS.

So what does it take for an engineer to survive? It’s simple. Change careers or improve. I believe that a skilled engineer, not only does not need to worry, but in this era, can have a stable career and a good income.

Recently have go out to interview a friend should know that now from beginning to end of the interview is more in-depth technical problems, while those problems look can check to the relevant information on the Internet, but the interviewer is basic it is according to your answer sustained and in-depth, if there is no real understanding of the technical principle and the underlying logic has certain is unable to pass.
