As a hiring manager or company owner (I wore both hats) I developed a routine during the interview that basically leads to a breaking point.

I want to either drill down your bullet points to find out if you're actually an expert in XYZ as the resume claims, or work with you on a coding problem that's simple to understand yet more complex than leetcode challenges.

I don't expect you to ace, but I want to check if you're honest and willing to admit your limitations - my philosophy is that I hire humans, not compilers, no one knows how everything, and I'd rather have someone who's fast finding correct answers on the internet than someone who had memorized a book.

That's how I like to do it. Its been so long that I don't even remember when I myself was treated this way during an interview.
