Meta Ios Software Engineer interview questions

Phone screen followed by interviews. 2 coding interviews, a design interview and a personality interview. Super easy questions, but blew one of them and didn't perfectly handle the rest. aaa aaa

After a 30 screening call from the recruiter, I was scheduled to have a 45 minute technical interview with a Facebook engineer. The interview started with some basic iOS technical questions (when would you use delegates vs blocks; describe the difference between autorelease and release; etc) then quickly go on to the meaty programming exercises.
