Certainly feels like one when I know the context switch is coming and it's scheduled in such a mid morning or mid afternoon slot that the time either side of it isn't long enough to do deep work, particularly when the rest of the team will interrupt me ad hoc to get unblocked on their work. If there were no meeting I can deal with their interruptions and context switch back to my work and get a long enough stretch to concentrate. With frequent meetings in certain timeslots I get virtually nothing done some weeks.

It likely affects some people more than others depending on the demands placed on you.

Think I'm going request meetings never fall mid morning or mid afternoon.
