> This might just be me, but I was kind of struck with just how much progress and accuracy you are expected to achieve at the whiteboard. And like I said, I am kind of blown away that people are able to do this. While I can pose those questions and develop a mental model for how to approach it, I just couldn't solve them at a whiteboard in 45 minutes to anything approaching what I believe is the standard.

That is why I stress its memorization because without memorizing things you've long since abstracted to libraries, you really can't perform in the stressful interview situation to the level the interviewer expects.

If, however, you take something the interviewee implemented in the past 6 months as the "standard problem" they could probably do it without much trouble.
