As director of customer success at MongoDB, Katie Palmer emphasizes the company's commitment to talent development and servant leadership. When reviewing resumes, she looks for relationship-building skills, business acumen, resourcefulness, grit, determination, and teamwork. The hiring process involves a recruiter screen, conversational interview with the hiring manager, and a case study discussion with a customer success team member. The "challenge" interview requires preparing a mock onboarding meeting with a new MongoDB Atlas customer, where Palmer looks for passion for technology, strategic thinking, adaptability, and coachability. Katie encourages candidates to engage with the team and recruiters throughout the process, highlighting the importance of personal connection, curiosity, and feedback application in succeeding in the role.
