On the surface, the hiring process may seem like such a simple step for a business or potential employee. Job hunters apply for a job; the company reviews all of the potential applicants and their resumes; they interview the candidates; and, eventually, a new employee is selected. What's so difficult about that?
In reality, though, the hiring process is actually very complicated, and any business needs to know the potential risks and legal aspects to the process. First and foremost, the actual interactions you have with potential candidates need to be compliant with the law. You can't ask certain questions in interviews, such as questions about religion, nation of origin or marriage.
