At any large company, communication from management to employees is a problem, however it is actively being addressed. Direct managers are rarely available, due to their large workload.
Each of my managers have been incredible mentors and continue to take an interest in my career once I leave their area.
Immediate managers very accessible. Internal communication good. Feedback could be better (positive or negative).
Immediate manager is very good and accessible, further up the chain becomes more difficult, as there is a definite hierarchy that is adhered to.
Line managers generally show reward for effort.
Praise comes in many forms in the company. Some examples include, in our formal goal setting without managers, above and beyond awards across the whole company, shoutouts in department meetings and informal oral and written feedback.
Most managers are very accessible, and are open to communication. We have an open-floor policy so it is easy to approach them during working hours.
I believe it is very dependent on your team and role within the organisation. My team and managers have all been very good experiences.
Very dependent on the department and your manager.
