What does a system administrator need to move from Junior to Middle?

Question

linux

I love to educate myself in my free time, and how lucky I am that work and hobbies almost coincide
. One of my favorite activities was and is to look at the level table of the system administrator, learn something new and symbolically paint over technologies that I more or less figured out, at least the table and humorous, but nonetheless useful
, and lately I've been wondering what it takes to meet the middle level?
it would be very interesting to listen to the opinion of experienced people and draw up a more or less clear algorithm of actions

Answer 1

junior, middle, senior - these are all conditional concepts in which each company / person invests their own. There is no GOST here.
I can say one thing that you need to strive not for the algorithms of becoming middle and senior, but so that it is not “more or less figured out”, but so that with “closed eyes” you can do what you are trying to achieve professionalism.

Answer 2

Experience. I noticed on my own: if you study some kind of technology, even pass an exam on it, then, without putting it into practice, the details are forgotten, at best, after six months. The basic principles, of course, remain, but to implement the solution, all the same, you need to climb and raise the certificate.

Certification? )

Answer 4

You must understand that the higher the level of an IT specialist, the smaller the number of areas in which he specializes. Do you study everything at once? Choose the most interesting area for yourself and purposefully hit it. For example, do you enjoy building and maintaining networks? CCNA => CCNP => CCIE (RS and SP). The training course will give a good minimum of necessary knowledge and horizons, which later must be consolidated with experience. For example, in parallel with passing exams, look for a new job that will allow you to more often encounter the desired area.
The exams themselves may or may not be taken. It's better to give up. This is more correct from the point of view of self-organization (if in a couple of weeks an exam is scheduled for 55k rubles and with a very low average pass rate, it becomes extremely easy to spend many hours a day reading documentation and playing with labs, which dramatically raises the level of knowledge) , and in terms of real confirmation of knowledge in front of a potential employer. And, of course, self-satisfaction.
Only dumps do not need to be opened. They instantly distort the picture.

Answer 5

Since the very concept of a System Administrator is very broad, I think no one will answer for sure.
For example, my progress looks something like this - over time, work tasks are completed faster and more efficiently (more correctly / more elegantly) than before due to new technologies, experience, reducing the number of crutches, etc.
