Embedded C++/C - share your experience

Question

C++ / C#

I worked for a year as a C++ programmer, mainly supported COM/ATL projects, wrote a couple of my own modules. Now I want to try to work in the direction of Embedded C ++ development, but I don’t know if it’s worth going there without knowing microcontrollers, Linux and pure c.

If anyone works in this area, give a couple of tips.
