An open job interview is one of the least common types of job interviews as it is suitable only for particular companies and positions. An open job interview invites anyone who wishes to come to an event where they can hand in their resume and be interviewed on the spot alongside other candidates.
There is no initial screening process for an open job interview, as you bring along your resume and cover letter in person. It may, however, include numerous interview rounds as the recruiters try to differentiate between candidates. This technique is most commonly used when companies need to hire for many of the same position at once, such as seasonal casual workers.
