Sourcing is important in recruitment because it helps to identify and attract a pool of qualified candidates for a job opening. Effective sourcing strategies can help to expand the candidate pool beyond just those who actively apply for the job, which can increase the chances of finding the best candidate for the position. Sourcing can involve various methods such as job postings, social media, employee referrals, and networking events. Without effective sourcing, recruiters may miss out on potential candidates who are a good fit for the position, which can lead to a longer time to hire and potentially hiring the wrong person for the job.
