In addition, I mainly have run interviews as a 1st or 2nd round screener, and I suggest to continue with interview process even if someone kinda blows a question as long as it seems like they're not lying about their experience. For interviewing experienced candidates I'm often trying to come up with a problem the team has faced and turn it into a series of questions. When it doesn't work, I feel like there's a 50:50 chance that I didn't phrase it well/didn't include enough info (but unless I happened to interview several candidates that week and we just don't have time) I am fine with letting a second screener or the whole team talk to a candidate. But I guess OP is probably referring more to final interviews. But for me at least, phone screens really are ok to get things wrong, in case there is anyone out there with phone screen jitters.
