At Google, internal research shows that interactions with interviewers are the top-mentioned factor in candidate feedback -- more important to candidates than the type of work, the benefits, or their interactions with recruiters when assessing the overall hiring experience. Google communicates that to interviewers, and emphasizes their critical role in the interview process and company culture.

For this reason, and the practical fact that the hiring team is interviewing thousands of candidates every year, Google wants interviewing to be part of every Googler’s job. The hiring team tries to identify a wide range of interviewers across demographics and job levels. Once the team identifies them, interviewers learn about desired attributes for candidates and review the interview process as a whole. The more interviewers understand what they’re looking for and how it fits into the larger picture, the more effective they can be.
