Yeah those open floors are so terrible. When i started late 90s I had my own office when as an intern. Everyone just had a little office. You could close the door if you needed to focus and you could open it if you needed a chat.
Then came the terrible time of the cubicles and then the open floor which was even more horrible.
I really hate tech work these days. Also because it's not really tech anymore. I don't get to do the nuts and bolts, I just have to tick boxes in the crap cloud admin panels that Microsoft gives us. I wish I could do something totally different.
