Interviewing is a noisy prediction problem

Erik Bernhardsson

So we can choose to spend one hour on system design, one hour on algorithms, etc. System design. I like system design questions (“how would you build this feature”). If we had complete data about candidates and their future job performance, it would look something like this. . Algorithms. Github portfolio.

AoAD2 Practice: Simple Design

James Shore

In the second edition of Extreme Programming Explained, Kent Beck provides four criteria for evaluating the simplicity of a design: [Beck 2004]. It doesn’t matter how brilliant and elegant a piece of design is; if the people who need to work with it don’t understand it, it isn’t simple for them. Beck on Simplicity.
