Meta Data Engineering Manager interview questions

Recruiter from Facebook messaged me on Linkedin and did a short phone call with me about the position. He was asking for my experience, why facebook and salary expectations. After then, an interview with engineering manager was scheduled for 1 hour phone call to test me about managerial skills, python, data modelling and SQL. The interview was very superficial: the management skills questions just focused on how I dealt with problems in my team, how can I assure excellence and very very general questions. I wasn't asked about my real experience, success stories, failures and problems I faced with. After 15 minutes we moved to SQL, python and data modelling. I answered on them perfectly without mistakes. After 2-3 days I got a call that they don't want to proceed with the process as they want other experience for this manager role. I'm a bit confused because they almost didn't ask anything about my experience...
