Like so many complaints about coding in interviews, this is talking about coding for a bad interviewer. Listening to both sides of the argument I've come to the following conclusion. Just as the unthinking mantra is now "90% of applicants for programming jobs can't program," equally often we hear "99% of interviewers can't interview."

Interviewing is a two way street, and programming jobs require more than just programming wizardry. You will need to work with a team, you will need to communicate with management, and you will need to understand people who aren't programmers.

Start by understanding interviewers.
