That's not always true. The best interview experiences I've had were at companies where you were given a homework assignment, and then invited on-site to talk about your solution for that assignment. That's not at all comparable to the standard Apple/Google/Microsoft/Facebook process where you're expected to come in and solve some graph theory or dynamic programming problems on a whiteboard for 4-6 hours. I would much rather do a homework assignment and then come in and have a code review or design discussion about my solution than do the standard process. And, I would argue that it gives the company a much better look at my skills and aptitudes than the whiteboard interview. I have never once written a dynamic programming algorithm from scratch, in 11 years of programming. I have implemented graph theory algorithms only a handful of times. But create a relatively basic piece of functionality, and then justify my solution in code review? I do that literally every day, and sometimes more than once per day. I understand that writing code for a homework assignment can be seen as giving the company I'm interviewing for "free labor". But, as others have pointed out, from the interviewee's perspective, there's not a huge distinction between spending 8 hours cramming Introduction to Algorithms and Cracking the Coding Interview versus spending 8 hours making a website using Django or Ruby on Rails (to name two interview tasks that I've actually been presented with). Frankly, I was much happier writing the websites, as it seemed much less pointless than memorizing how to write Floyd-Warshall all-pairs shortest path in Java on a whiteboard.
