I worked in a open office with a sales team whose job it was to make phone calls from their desk all day.
But even for engineers, it was common for them to join meetings with people from other offices from their desk. There was no other place for anyone to go - there weren’t nearly enough conference rooms to support all the people making calls simultaneously.
Same, and it was terrible. And I promise you it's not just a techie copping a "hurr hurr salepeople are awful amirite" attitude: most of the salespeople at this company were great folks and I enjoyed their company...in my free time, i.e. when I wasn't trying to concentrate on coding with them all talking at once.
