Interruptions are also common.
If you don’t want to be interrupted, too bad. It’s going to happen. There’s no way people can avoid interrupting you for the whole day.
But what you can do is indicate when you’re deep in work. When you’re doing the sort of work that requires intense concentration and will take 15 minutes to get back to.
For me this is headphones. I put on music and focus, and my coworkers know not to bug me unless it’s important.
Find your headphones. Whether it’s actual headphones (you can always put them on without any music playing if that’s what you prefer) or just some sort of indicator. Be cute about it! Put up a “recording in progress” sign or a mailbox flag.
Let people know you’re focused. Otherwise you can’t really complain when they interrupt you.
