Well, a famous example is Microsoft. Though the recently built and renovated buildings are moving toward open plan offices, about 80% of the buildings in the Redmond campus are full of offices. Which office you get is purely based on tenure. I remember it took 11 years of tenure to get a window office in my old building. Some new hires were doubled up due to space constraints. But I was in the 70% of office holders who had a single office from the beginning. It was fun to be able to decorate my office. You could really see people's personalities in their offices. Offices would also double as quick meeting rooms for up to 5 people. No overhead for booking conference rooms. All in all, it was a great perk of the job. If only they had free food... Even if you have offices, people would still barge in, cutting into your uninterrupted time. Funny enough, in the open-plan at Google, where I am currently, I get far fewer walk-up interruptions. It's always good to ping people on chat so they can respond async.
