Indeed. Experienced interviewers can size up a candidate in the first 10 minutes and fairly accurately predict how their debrief will go. The rest of the interviews are just building up confidence, and making sure there's enough redundancy to tolerate the occasional bungle or accidental awkwardness. Folk get hired all the time despite getting imperfect interviewer feedback. I've had interviews where the first 45 minutes were painful but then the candidate blew me away in the last 15 minutes.
