Since pay is based on productivity once a project manager is fully trained, hustle culture is prevalent. This means, that for project managers, the job is best for people with certain personality profiles. Mainly, people who are relatively outgoing to deal with clients, hard working to keep up with productivity, and independent since each project manager is fully in charge of their own projects. If a new project manager has a hard time learning a lot of information or is generally slow, it can be discouraging. Typically the first 3-6 months, me and most other project managers I saw join didn't know if they would be able to learn everything they needed to learn and do everything they needed to do.
