I have had various interviews in the last couple of years. One I got offered the job without so much as any technical test, based on my CV. I almost felt a bit cheated there, as I wanted to prove I was good. I interviewed for a startup with non technical founders. They had pulled a Python test from the internet which seemed 90% about lambdas in Python (I can use them, but in most cases list comprehensions provide a more readable syntax).
I actually like being able to explain my thought process in an interview. Even if I don't get it right, then they may see that I am "almost there". Likewise if I don't know something, I can tell them.
I have a fair idea about my colleges work, not from their code, but by the way they talk about it, and seeing the tools they use. (The "best" in my office of 4 chooses Java for most of his stuff for some reason - not what I would expect from someone good. The worst code was written by someone who ranted about how I should be choosing Python over Perl.)
