Having worked in 4 departments and undergoing countless management changes, I can say with every confidence that at eBay middle management has no oversight and runs wild. Their official function is to be in lengthy offsite lunch meetings, not to support their employees. Most team leads are unaware of how to use internal systems and are unaware of business practices and policies. Coaches (Jr. Management) are rarely available, and are often equally unknowledgeable. Employees are blamed for staffing issues and lack of appropriate volume forecasting, and as a result queue times are unreasonably high at all times.
Advancement opportunities are slim to none, and internal internships have all but been eliminated. Management is almost exclusively white, male, and Mormon, and any HR issues raised by employees about management are immediately closed without action or resolution, stating things like "[supervisor] says that never happened".
