I've seen lots of recent posts sharing resources for system design interviews.  But is there a good forum for getting feedback on a practice (read: unfinished) design?Essentially, I spent thirty minutes fleshing out the design for a practice problem ("how to build a search engine") to prepare for an engineering interview and I'm looking for feedback on it...and ideally other problems that I haven't started yet.  Any suggestions on where to go?  Show HN seems to be more for finished products or prototypes while stack exchange is explicitly focused on questions with definite answers.  And I'm not really interested in paid for interview coaching.Is this a pain point that I'm experiencing alone or are there other out there like me?Links to the Recent Posts I mentioned:-
