I made it clear I’d provide any answers to questions or functions or syntax they needed (because IRL they’d just google, so I’ll save them the time).
That right there is the difference between a shit interviewer and a golden interviewer. And that goes for a lot of technical roles, far too many just throw a "whiteboard" at you and just expect you to figure it out without any outside help, even though it goes against how even experts get things done in the real world :/
