Good advice overall, and definitely an improvement over the usual interview boilerplate that candidates have to trod through. However, in some places it seems to be too cavalier -- in the sense that it suggests we now have a magic prism with which we can "diagnose" the candidate's shallowness or lack of candor. When really they're just saying something basically innocuous. Cause it's like, been a long and mostly boring interview process so far, has it not, and they're trying to slog their way through the canned / pre-programmed (if arguably necessary) part of the process like you are. For example, under "Things to watch out for": High standards: if they say there’s nothing they wish they’d done differently, this may also be lack of embarrassing honesty, or not holding themselves to a high standard Or they had a genuinely shitty experience (with high costs to finances, relationships and/or health) that was 80 percent out of the blue and beyond their control. And they'd really rather just move on. Or if they did tell you the real context and their real reasons for doing X -- you'd very likely ding them (quite likely fatally) for doing so.
