The more difficult the season, the more outrageous things will happen.
It's really too fierce. Those who have seen salary cuts have never seen such a ruthless Internet company. Recently, a well-known system integrator in Hangzhou issued a notice to cut salaries for all employees.
In fact, it is not uncommon for Internet companies to cut their salaries recently, but do you know how much this company cut their salaries?
Ordinary employees have a 50% salary cut; supervisors and above have a 60% salary cut; executives are even more aggressive, and they are directly paid 0. Anyway, the IT circle is all over the screen, saying that this company is going to close down, and it doesn't leave any bottom line.
It is useless for many programmers to apply for arbitration. It is difficult for companies and even more difficult for programmers. It is not easy to find a job at this time, and I have been working for nothing for a while.
This kind of company is not competitive enough, and it will be squeezed out. Just like programmers, if you don't improve your core competitiveness, you will easily fall behind.
How programmers can correctly improve their core competitiveness
Under the premise that the recent economic situation is not optimistic, many IT programmers are facing increasing pressure and crisis in their work, and at the same time, they can't help but start to worry about their career development. So when IT programmers want to become an irreplaceable existence for others, how should they improve their core competitiveness?
In the past, I specialized in one technology, and it was enough to be proficient.
The main reason is that I am afraid of being greedy for too much, greedy for everything, and not going deep enough. Resulting in not being able to learn at home!
It is true that the situation is a little different now. It requires specialization and needs to meet the needs of the market. Just like today's Android development, there is basically no market for application development, so you can't just fall into it!
Nowadays, many Android programmers either transfer to vehicle development or go to other industries. ,
But for Android programmers, positions that are suitable for their career change basically have one thing in common, that is, they are familiar with the underlying Framework .
So in-depth study of the Framework is now a must for every Android programmer.
How to learn Android Framework
In order to help you understand the function and structure of the Framework in the entire Android architecture, systematically learn and master the Android framework, here we specially collaborated with Ali P7 architects and Google technical teams to organize a learning material for the Android framework family bucket.
