Outstanding.
I've done quite a few interviews and as long as the interviewee maybe said something like "it would be better to use a shadow DOM" and could explain what a shadow DOM is, I would be pretty happy with that
Expecting someone to build a full shadow DOM as part of their interview take home is excessive
Often you don't even get to the interview step. One time I had a take home that said you could either do frontend only, backend only, or full stack. I decided to pick the backend only one and complete all of the optional backend tasks to make something pretty well made.
Then they email me back and said the other candidate did the whole thing and they aren't sure if I know how to style a page now because I only completed the backend part.
The inability to get feedback and course-correct is my biggest peeve with take homes.
Is this one of the tests where I just need to throw together a five minute quickie to get over your “can you program” filter? or do you need me to put together something flashy and memorable to show off my ceiling? If o put together my flashy thing, would I get dinged for over-engineering something where a five minute hack solution was good enough?
Often times people ding you for doing anything different than they're used to, or what they see as "the standard".
The worst is when they basically ask how you'd build their product. Some people can't handle a different answer, even as they're busy hiring you to improve things.
