First of all, people will see if you have experience. Without experience, they are basically not interested in getting to know you again. If you are lucky, people will continue to read your work, and the rest of your resume will only be read if it is appetizing. If they are interested in you, they will let you test first, and some will interview first. I have to take the exam anyway.

It's hard to get into the business these days. There are many gods in the upstream, and many newcomers in the downstream want to come in. What is awesome is really awesome. Companies are scrambling for it, and newcomers are really pit. The company doesn't dare to take it, and generally doesn't want to train you well. It's hard to get promoted in this line of work. It's up to you to temper your hard power. It is not difficult to find a job when you have the ability.
