Before any recruiter considers hiring a candidate, they need to ensure that the individual can build relationships with and earn the trust of their existing teams. Their goal is to hire an employee that will contribute to employee retention. If they hire a candidate who delivered a solid interview but doesn't get along with their existing teams, this could result in dissent and contribute to more attrition. So, your interviewer has to ensure your brand of teamwork and your respect for the onboarding process will complement their environment and culture. Research their careers site, align yourself with their values, and adopt their language wherever you can naturally do so. For example, one of Club Alliance's core values is teamwork, "Foster cooperation and have fun. Encourage and reward achievements. Join with colleagues to deliver exceptional quality. Understand Club strategies and challenges." Assure the interviewer that you are an honest and trustworthy person, would take every measure to earn the trust of your peers through professional humility and shared values, and would thoroughly gain a better understanding of what they've built and why they do things the way they do before suggesting implementing change.
