Meta Product Designer interview questions

Was contacted by a recruiter and met for first round of interviews where we briefly went over my portfolio. The format was they interview me first, then I interview them. Afterwards I received a follow-up email and after some scheduling difficulties did a phone interview where I was asked to critique a mobile app.

Applied through requiters visiting my college. Met with an alumna who was currently an employee. We had a very relaxed and productive conversation about design as a whole, working at Facebook, and my work. I was contacted a few days later about a follow up interview. The requiter was always helpful and kind. Spoke to a woman on the marketing team in an hour long phone interview. She seemed cold, but possibly was trying to show no inflection in her voice to keep the interview neutral. She asked about a few specific projects in my portfolio, and asked follow up questions on how I would adjust the design based on different hypothetical criteria. Was contacted around a week later from my requiter notifying me that I would not be moving forward with the process. I asked for a follow up conversation to get feedback, which was granted. During that conversation, I was told my main reason for being passed on was that I did not have enough experience. This struck a chord with me because the whole time they were pitching at my college, they said they were only looking for people with potential.
