> Just on resume? Are you aware how easy and common it is for candidates to lie on the resume?
If you can't figure out a candidate lied on their resume in a half hour conversation, you aren't going to figure it out in a four hour conversation either
More data absolutely helps, many people can fake it for an hour but not for 5. Work doesn't end after the first hour, so if they can't keep it up for less than a full day they wouldn't be able to during the real work either.
