Step-by-step explanation:
Deidre can utilize all of the following to expand her recruiting efforts except job bidding. Job bidding refers to the process where existing employees compete for job positions within the same organization. It is not a suitable strategy for expanding recruiting efforts. On the other hand, college/universities and job fairs, the state employment agency, and employee referrals are effective methods for reaching a larger pool of qualified candidates.
