One firm focused on recruiting new talent, cross$-$trained the broader human resources team on behavioral interviewing, and challenged them to get more involved in supporting hiring managers during the interview process. This is an example of what type of cross$-$training? Why?

Job enlargement; the people are cross$-$trained, but the level of responsibility is still the same.

Job hopping; employees are given assignments in different functions in different locales to develop a deeper understanding of the firm$$s business.

Job rotation; employees are exposed to working in all areas of the organization.

Job enrichment; it includes the addition of tasks that give the employee more control or more responsibility.
