Without specific context about Tina or her preferences, it’s difficult to determine which method she preferred. However, if the goal is to provide personalized guidance and attention to each new employee, one-on-one training might be the preferred method. On the other hand, if she values collaboration and interaction among employees, she might lean towards group training or peer training. Job shadowing can be effective for practical, on-the-job learning.
