Most of the tweets are about implementing specific famous algorithms (bubble sort) or about language/library trivia (reading from input streams in Java) or esoteric computer science theorems (np compete). All of these are the exact opposite of whiteboard coding interviews. The whole point of whiteboard coding is that candidates are given a small problem/spec, and to solve it using any language/psuedocode/algorithm they want. The fact that you can ace a whiteboard coding interview without knowing anything about input streams, or bubble sort, or np-complete, is the entire rationale behind this interview style. The fact that whiteboard coding interviews are so precisely objective and formulaic makes them so much less prone to bias, as compared to bullshit interviews where you're asked to reminisce on past projects and your greatest weaknesses. Almost every tweet shown in the article only succeeds in validating the whiteboard coding interview.
