There's plenty of "fires" where a top priority project hits your desk and you have to address it, which means moving all other projects to the side.
Customer service, in my experience, was chaotic--but i'm sure that's universal
Sometimes if you need help from anoher department, it may take time bcause everyone is busy, which means you have to deal with the "fire" by yourself. This doesn't always work out well.
Sometimes your issues/complaints with fellow employees/clients will fall on deaf ears.
