It seems Triplebyte just tests everyone on web technologies regardless of role or experience. It makes sense that C++ engineers are less familiar with large scale web apps, but are valuable hires in the industry for robotics, finance, game engines, etc.
(Article author here.) I'm one of the interviewers. If I had to guess, maybe a third of our generalist-track interview is web-related. I've personally interviewed many engineers who did not know the first thing about any web stuff, but were particularly strong on other sections, so we accepted them.
You really don't have to be great at every section to pass the Triplebyte interview; you just have to show your personal areas of strength. And we give you lots of different opportunities to do that.
Of course, we will then match you with appropriate roles and avoid the ones that require web-specific skills. FYI, we already have robotics, financial, and game companies on our platform!
