Newcomers' relationship-building behavior, mentors' information sharing, and newcomer adjustment: The moderating effects of perceived mentors' and newcomers' deep similarity

Drawing on similarity-attraction theory, we propose that relationship-building behaviors from newcomers are more positively related to information-sharing behaviors from mentors when they perceive a deep similarity with the newcomers, and that mentors' information sharing is likely to be well received by newcomers when they perceive a deep similarity with their mentors. We also hypothesize that newcomers' perceived mentor information sharing is positively associated with newcomer adjustment (i.e., role clarity and job performance). A time-lagged study with a total of 99 newcomers and their mentors was conducted within three months of newcomers entering the company. The results support our hypotheses, suggesting that perceived deep similarity is a key factor that associates with the effectiveness of newcomers' proactivity and mentors' information sharing behavior in newcomer adjustment.
