A friend with a monthly salary of 50000 told me that you were just doing chores

A few days ago, I talked with a friend about the interview , He said he got both Tencent and Ali's last month offer, Finally, Ali was chosen .

I learned about his interview process , Just a little , Whether it's Ali or Tencent's interview , Programmers at this level , Will examine the project management ability , And the weight is very large .

In fact, no matter what position you are interviewing , The front end is good , Back end , Must examine management , It's off , Basically, there's no big problem .

He told me , Those big factories think , Only everyone in the project has enough management awareness , To ensure that there are no mistakes in the work , Maximize efficiency .

But think about the daily work scene of the technical post , Also reasonable ：

The product manager doesn't do business every day , There is no head or brain to ask for , Bother ;

Regular meetings every week / Docking meeting , It's not efficient at all , Bother ;

Same need , We should connect with people from several departments over and over again , Bother ;

There is no consensus , If you want to say it, you can't say it again , Can only passively accept , Bother !

The reason for these problems in work , In fact, most of it is due to the lack of project management ability .

When it comes to project management capabilities , Many people's first reaction is the position of business supervisor . But as an ordinary programmer , In fact, we also need to understand project management .

According to the survey , Most programmers work for three or five years , They can master the necessary knowledge of their positions 、 Experience and skills . But a lot of people are going to get into trouble next , Can't break through the bottleneck in the workplace , Not to mention a raise or promotion .

So most people will choose the technical expert route , And people with stronger abilities will be in this situation , Have more competitive advantage . If you are not confident in your basic knowledge , I suggest to study systematically again , In order to help everyone improve their learning efficiency , I've arranged a set Java Advanced learning notes .
