Managing one person becomes hard because neither manager nor subordinate have a comparison point. Particularly because in these scenarios the subordinate is new to the working world and the manager is new to managing. They are both the best and worst employee/ mangager either have ever had and they have no context to know which is true. The truth becomes more clear in later in both individuals professional journey. I can look back early in my career and realize I had a terrible 1:1 manager, but thought it was me. I can also look back on a time I managed an employee 1:1 and recognize where I could have been better.
