The office in the area I was looking at was SMALL. That wasn't so much an issue but the vibe of the place was almost like a library.
There is a time for that, sure, but getting peace and quiet to get in the hacking mindset is more important to me.
I was sufficiently spooked by their environment that I choked on a little practical exam they had set up as part of the interview process.
Anyhow...I didn't get THAT job, but I did get a BETTER one. More money, more autonomy, more interesting work.

I also have somewhat severe ADD; open office layouts are fairly negatively impacting to my productivity.
