From the front to the backend, is related work experience taken into account?

Question

Career in IT

Hello, such a situation: +6 front-end development experience (2 layout, 4 SPA). I know classical things even without a backend (algorithms, data structures, operating systems superficially), with networks, of course, it’s not very good. I worked as a pythonist for half a year (it happened), 1 year NodeJS (Express) / Javascript (React) full stack. Now team leader of a small team. I plan to move to the backend (Java/C#/C++). In the front-end, I can claim quite juicy salaries, since I have a huge experience in writing various applications on the browser side, I wrote React for a couple of years, now it’s the year of Angular, before that 4 years of Backbone. I have been working on the web since 2008. In the backend - I know the basics of databases, NOSQL, I distinguish a process from a thread, I can raise a server with CLI (Python, NodeJS) on a pure VPS. - Set up nginx, ssl, memchached, sql, nosql, got some devops practice on freelance. docker, Elastic and other things used in home projects. I understand what N+1 request is. I write tests.
It is interesting to ask a question to the people behind the backend helm - not the developers, but the managers. Do you take into account the experience that a person comes from the front as from an adjacent area? It will be funny for me to hear now, let's say from Yandex - come to us as an intern or let's join us as a junior for a backend for a penny, I perfectly understand that there is a certain experience - C # and JAVA are quite adjacent, but Frontend / Backend - no. But, so to speak, is it possible to count on a middle position in a large city with a good salary, moving from front-end team leadership to back-end development?
There are no questions, the main thing that the company wants to see is asked and checked at the interview. But since I myself spent several hundred of them in the front, I know that the specifics of each vacancy are different.
How to be? What do you advise?

Answer 1

What is there to advise except how to go to interviews?
Personally, during interviews, I look at how a person thinks in general, and not on specific skills.
but if you are aiming for middle and above, then all your previous experience is not worth much if it is not related to applied activity in a new position, and you are not able to prove the opposite.

Answer 2

What matters is how you actually work.
It is known that, as a rule, an experienced programmer quickly masters . Even with a different language, etc.
The track record, among others, of course, affects the decision, for example, about which candidate to prefer - nothing more.

Answer 3

Pass interviews
