Apple Software Development Culture

I am having an interview next week with Apple AMP(Apple Media Product) org and would like to gather some questions and insights about the software development environment at Apple or the AMP org in general. I've heard that the development env at some orgs are not as matured as other tech companies since each org has there own infra and the process can be less than ideal. I am also concerned about the secrecy culture and discouraged in knowledge sharing. I wondering if that would have an impact on career development given I am early in my career. Would appreciate if software engineers from Apple can provide some insightful info. YOE: 4 TC: 220K #apple #software #swe
