Combine the open office with a rehabbed concrete warehouse with no carpeting (looks "edgier") and a conference room behind you.
Noisy and distracting, the whole day long. I can hear every dropped item, every woman with high heels, every conversation in the entire office. And it's even more fun when there's a meeting in the conference room behind me, with someone calling in on the speakerphone.
Every.
Single.
Sound.
It's like they thought, "how can we make it impossible to concentrate?" and then did a bang-up job of implementing it.
