I've done the TripleByte interview, so the decision to ask questions about relational databases instead of asking for a practical exercise makes sense in context.
It's because you can only fit so much into an already long interview (2 hours). A big chunk of that time is already spent on an exercise about reading/writing/debugging complex code. You can't fit everything in, so database stuff is moved to the non-coding section. Also, the questions aren't "guess the right answer" questions, the interviewer keeps digging with open ended questions to see how deep you can go.
> it could be that the candidates couldn't effectively communicate knowledge about RDMBS's. Or, it could be that the interviewer wasn't effectively listening to what the candidate was saying.
You could certainly get a bad interviewer, but that's a strawman here. If it's not TripleByte judging the candidate's communication skills, then it's the hiring team judging that. The suggestion was about how to give feedback about communication skills. And there are definitely stronger and weaker communicators, and it definitely makes a big difference in day to day work.
