Look at some job descriptions of some cool companies facebook/google... Do you see a simple word being related with windows technologies?

yes, it is fine to be a janitor as well for thousands of thousands of people. Would you like to be one of them?

If you are serious about your career path as software engineer stay away from windows technologies.

Alice got in facebook just attended coding boot camp and did some algorithm practices. Why does facebook recruit a non experienced like Alice but turns off lots of talented (with a top school cs degree)/with decent working experiences? I am curious.
