Awkward 35 years old

I don’t know who put forward the law that the workplace will be eliminated at the age of 35, because the 35-year-old law is originally a false proposition, especially in the IT industry!

Now that eight or nine million college students graduate, although they are young and energetic, many companies also "turn them away."

The 35-year-old does not want it, and the 20-year-old refused. I feel that many small and medium-sized enterprises are really "hypocritical" and cannot afford to find experienced talents, nor do they want to give fresh graduates a suitable position.

This is also one of the important factors that cause many small and medium-sized enterprises to have a life span of only 3-5 years, because they are really hard to explain in terms of employment.

At last

Give everyone a complete set of Android learning materials.

In the past, I had been looking for things on the Internet. The things I found were scattered. Many times I just watched it and disappeared. Time was wasted, but the problem has not been solved, which is very maddening.

Later, I compiled a set of information by myself, let alone, it's so fragrant!

The information is organized, systematic, and comprehensive. It is not convenient for me to directly release it. You can first see if there is any use.
