Apple Developer interview questions

One of the most UNPROFESSIONAL interviews I have been in. Interviewed with 3 teams at Apple. Cleared the technical phone screen with all 3 teams BUT when I spoke to the hiring managers on the next call (for each team), I started to think do I really want to work here? Each hiring manager was very rude and the furthest thing from humble, they interrupted me regularly, mocked me on my age (I have 4 years of experience work experience, but I’m 25). To add insult to injury they all boasted how their teams are building the next biggest thing (Maps, iTunes, Core). I went to the on-site cause and cleared all 4 rounds but never have I felt super un-easy interviewing. TLDR; got an offer declined it, because each of the hiring managers were complete jerks even though those in the teams were really nice.
