Depends the type of job! For the little story I had a job at a small startup 50+ people. We were like 20 people at the tech and we had 20 sellers. The whole company was in the same floor open space one big room. Sellers loved to chat all the time, be loud, cut each other in what they were doing… A big contract closed on the phone? They had a small belt to be ringed! At some point it was so noisy that even with headphones we couldn’t concentrate. Of course the tech part of room was quite silent. One time we asked them how can they ever focus with this noise and be productive?? They said that for them it’s like giving them the smile, being chatty being part of the job, the adrenaline rush to make it seems like the next big deal is right there on the next call.
