Thoughts on interview of Ali CCO project team

Review the interview questions

• There was the concept of microservices in the early years , Why not fire before , Now it's hot ？
• What do you think is the nature of Architecture ？
• JVM How to handle out of heap memory , Will there be garbage collection ？
• What are the projects and their internal difficulties ？
• The difference between high availability and disaster recovery ？
• How to guarantee the stability of service ？

No accident , I answer the same as shit . It can be said that the focus of my previous study or work is the level of knowledge , According to the needs of the business , Instead of focusing on the higher level 、 Something more abstract .
For example, software is a business activity , What is the focus of this project ？ Why choose an existing architecture ？ If I were an architect , How do I do business design and technology selection ？ Wait a long list of questions .
I will take time to study the above problems , Writing analysis , We can't stay at the level of knowledge forever .

Advice for me

• There are too many items on your resume , I want to find a big project and write it in detail , Draw a picture , This will allow the interviewer to better understand themselves , You can dig for dry goods , Otherwise, it's not very valuable to ask some basic knowledge , With dry goods, you can be more irreplaceable than other candidates , There's more sense of difference .
• Blog should have its own thinking , Don't keep a running account . Knowledge sharing is a good thing , But today's blogs are like their own notes .

summary

Where are your concerns , You belong to that Level. That's right , Want to grow better , You have to jump out of your comfort zone , Get in touch with bigger projects , Better people , study hard , Take good exercise .

Thank you very much for the interviewer , Thanks for his advice , A good man is safe all his life .
