Walk-in interviews or job fairs are often held by companies to recruit potential candidates for available job positions. In such events, the company invites job seekers to come in and submit their resumes, and may also conduct on-the-spot interviews. Walk-ins are common in industries such as retail, hospitality, and food service, where companies often need to fill entry-level positions quickly.

Job seekers who choose to do a walk-in should be prepared to introduce themselves professionally and provide their resume or job application to the appropriate personnel. They should also be aware that the company may not have the time or resources to conduct an interview on the spot, and that they may need to schedule an interview at a later time.

While a walk-in approach can be a good way to make a personal impression with a potential employer, it is important to also consider other ways to apply for jobs, such as through online job boards or networking events. Additionally, not all companies may be open to walk-ins, so it is advisable to research the company's hiring policies and procedures before showing up unannounced.

The phrase 'walk-in' usually indicates an unplanned visit or an appointment organized without prior scheduling, often occurring without prior preparation or booking. Its interpretation can shift reliant on the specific context in which it is employed.
