Other jobs, like receptionist and office managers, for instance, are interrupt-driven. Receptionists add value by responding quickly and handling a continuous stream requests.
Now let's talk about engineering managers. Being an engineering manager is IMHO, an interrupt-driven job. The job of an engineering manager is to tell you where to find answers to your questions, or on a good day, actually answer the question. The friction comes when an engineering manager does not understand that the interrupt-driven nature of his/her job is not reciprocal. A good manager will handle interrupts quickly, but only very judiciously use the power to interrupt.
Another source of confusion is dev/ops. Anything operational will tend to be interrupt driven. An engineering manager that has been running a high-functioning dev/ops team that is a team of crack fire-fighters might be a very disruptive force in a design engineering team if that manager expects a constant volley of chat messages among the team.
