when i last did interviews we didn't do live coding, but chatted to applicants about things they liked about their preferred language (this was a consultancy position). people who actually like to program tend to have loads of opinions. juniors moreso. the less engaged people were with those questions, the worse the solution the their take-home task tended to be.
a friend of mine interviewed a candidate who apparently visibly froze after every question, like it was a quiz. turns out they were being fed answers from people off-screen and those people hadn't expected casual conversation. they were found out when they forgot to mute.
