Very approachable but very busy.
CEO sends monthly emails, as well as has coffee catch-ups with employees. General Managers are always open to having a Chat. My direct managers are great mentors. They always explain why they give me the work they give me. They also listen to what I want to do and where I see myself and this lets them tailor my work training to allow me to get there.
Management's interactions are decent, but they are often busy with their own workload. They are very accessible and provide good praise and recognition, but are not the best mentors as they are very busy in their own workload. A lot of learning on your own is required.
I have had two great managers so far. They are busy, but they will help when needed and you learn a lot from them. Communication is pretty informal most of the time.
My managers are very accessible to me, being within earshot of my desk, they manage my workload very efficiently and frequently check in on how I am handling it
