It's pretty easy as an interviewer to spot when a candidate is hedging on a question, and it's the kind of thing that might get discussed in the post-interview debrief.
"Wouldn't give a straight answer on question X" isn't an instant no-hire, but it's not a positive signal.
I just interviewed a guy and all three interviewers asked him functionally the same question. He hedged 3 times and we just wanted an honest answer...
ironically, I'd understand people not giving a straight answer on this particular topic
"The candidate is mature and doesn't engage in bikeshedding"
This doesn't make sense in practice. He hedged so not sure need to look at other factors vs he picked a side and he selected the opposite of what we wanted no-hire or he answered what we wanted small positive signal need to look at other factors.
