In the process of evaluating a job applicant, the Human Resource Department of a company discovered information about the applicant on social media by the following means. Which of these actions do you think would amount to intrusion? How ethical would each be?

1-Googling the applicant's name

2-Requiring that the applicant "friend" the company, so it can access more information on his Facebook page than was publicly available

3-Hiring a third party (e.g., Social Intelligence Corporation) to search through the applicant's social media presence and prepare a report for the company

4-"Shoulder screening." The applicant logs on to his social media with the HR manager looking over his shoulder, allowing the manager to view everything available but also allowing the applicant to explain any unprofessional or negative-seeming items

5-Requesting that the applicant give his login to the HR manager

6-Requiring that the applicant give his login to the HR manager
