But what does that question mean anyway? Say I've been working in java stack for 10 years but for whatever reason I want to move to js/frontend. What else is there than entry level to begin with? Tech careers (at least honest ones) are rarely linear and there are hundreds of reasons for that.
Some might say you shouldn't want to work at those companies if you don't like their hiring process, as though there's nothing to any company but the hiring process. It's like saying you shouldn't join the military if you don't like basic training. Nobody likes basic training. People join organizations despite those things, and I for one am not going to judge them or assume their reasons are silly just because I might decide differently.
