1. Observe state
- Who works here
- Who is applying
2. Predict
- What long term affect would each action have on the company
4. Remember
- Record initial state, resulting stat, and immediate affect on the company
3. Act
- hire / fire
5. Train
- Pick samples from memory and train AI to better predict long term affect of the action taken
