This question is a personality check. The interviewer wants to know how you'd go about earning their collective trust and develop relationships in the workplace should they choose to hire you. They're watching for if you're overconfident in your answer or modest. In this hypothetical situation where you've been hired, but the other members of your team still haven't interviewed you, you still have a lot to prove. Too often new hires enter a job and try to impress by reinventing the wheel before they've learned the ropes. The interviewers want to know your approach when coming into a new work environment and how you'll fit in with the team. A new hire is effectively a stranger to a pre-existing team. You'll need to earn their respect. Therefore, part of what builds an effective and reliable team is cohesive work relations, feeling secure in their relations, and being able to trust one another. In this regard, describe what your contribution would be.

Familiarize yourself with the 30/60/90 rule. The first month of a new hire's 90-day probation period should focus on building trust, familiarizing themselves with the team, systems, procedures, policies, etc. Month two should be spent studying current processes and procedures, and identifying strengths and weaknesses. In the last month, that hire should be well-grounded in the role and capable of identifying growth opportunities. Past the 90-day mark is considered an acceptable time to implement innovation.
