One of the most important facets of the employment selection process is the face-to-face interview. Companies have different procedures for personal interviews. Some companies prefer to have all-day interviewing sessions, where job candidates meet with a different person each hour. During this time, companies may have the candidates meet with human resources, the hiring manager and other employees. Another option is is having candidates meet with key personnel one day, then inviting them back for second to meet with some executives.
