Which of the following would not be considered a possible indicator of recruitment?

Increased social media sharing of personal interests, while it may reflect personal development or changes in an individual's life, does not directly indicate recruitment efforts or intentions. Recruitment indicators typically relate to actions that suggest an individual is being influenced or sought after for a specific purpose, such as joining another organization or group.

The other options present more direct indicators of recruitment. For example, receiving a termination notice to join a competitor is overt evidence that someone is moving towards a new opportunity. Changes in work performance and behavior can also suggest that an individual is distracted or focused on new prospects, signaling potential recruitment. Similarly, acquiring new skills relevant to another industry may point to preparation for a transition or recruitment into that sector. In contrast, social media sharing of personal interests lacks the explicit connotations of recruitment and is more aligned with personal expression or communication.
