Apple Software Engineer interview questions

Was contacted on LinkedIn to for a job interview at Apple. First interview was just an online code test. I did well enough at that, and went on to the 2nd interview where I meet the lead engineer and am given another code test this time on screenshare. Both code tests were done on the web through an online IDE made for collaborative work. I was allowed to look things up, but was instructed to "talk it through" with the team lead before going to google it.

There was an EM call about technical background, he asked a few questions. We didn't agree on some things. There were not the best questions: graphql vs rest, which one is better?
