After passing the hcip exam, I still failed to change my career. What do professional network workers value most

The length of the article is long , After reading it patiently, you will gain something .

I'll take it HCIP When it comes to certificates , did not HCIP Level of Technology .

I took an exam when I made up my mind to change my career from desktop operation and maintenance HCIP, The most authoritative technical certification in China . But I was a bit of a bolt when I studied , At that time, I thought there was HCIP A certificate gives you a job , Arrogant want to just put IP I immediately quit my job and went to a faster track , Then you can make more money .

Therefore, I specially reported to a training company specialized in textual research , Passing the examination quickly was what I wanted most at that time . In the training class, the teacher didn't talk about the technology in detail , Everything revolves around passing the exam , It makes me feel like returning to the stage of exam oriented education . All courses focus on the exam itself , Not in the technology itself .

Get high marks by reciting the answers HCIP My skills have not improved at all , But I decided to resign , Take the certificate and knock on the door of the network engineer . But all kinds of experience tell us that exam oriented education can't solve the problem of work at all , My later results also verified these . Have several years of desktop operation and maintenance experience and HCIP Certificate I am in 6000 The network engineer with monthly salary has neither experience nor technology , Many years of desktop operation and maintenance have brought me nothing except the growth of age .

But I didn't give up , I have always believed that there is nothing wrong with choosing the network technology industry , I decided to learn it again HCIP, The purpose of this time is to learn HCIP Level of Technology . I use my own experience to draw a conclusion that only certificates without technology are completely useless , I succeeded at the end of the story , Mastered HCIP Level of technology and found a job as a professional network worker and engaged in it until now .

Su Shi has a famous sentence ： Take a broad view of , Thick and thin hair . If you want to be a successful network engineer , A single certificate is useless , Only with matching technologies can we go further .
